<p>I'm trying to implement simple <code>fread()</code> and <code>frwite()</code> example using strings. The program gives me <code>segfault</code> or <code>free(): invalid pointer</code> errors. Below is the example code I'm working with.</p>
<pre class="lang-cpp prettyprint-override"><code>#include <fstream>
#include <iostream>
static bool file_read(FILE* file) {
std::string value="abcd";
std::string retrieved;
size_t read, write;
write = fwrite(&value, sizeof(value), 1, file);
fseek(file, 0, SEEK_SET);
read = fread(&retrieved, sizeof(value), 1, file);
return true;
}
int main(int argc, char *argv[]) {
FILE *file = NULL;
file = fopen("file_test", "wb+");
file_read(file);
fclose(file);
}
</code></pre>
<p>I checked if <code>file</code> is opened correctly and that <code>retrieved</code> has the same value as <code>value</code>. I don't think I'm freeing any variables in my code. I'm suspecting that <code>fread</code> is causing all the trouble.</p>
<pre class="lang-c prettyprint-override"><code>fread(&retrieved[0], sizeof(char), 4, file)
</code></pre>
<p>Doesn't read the value to <code>retrieved</code> and was where I am doing wrong.</p>

<p>I want to compare the input with the list, but the else loop continues infinitely even when i give it a input that matches the list.</p>
<pre><code>def check_input():

guessing_range = int(guessing_range)

<p>Three Div elements with box appearance,
when user click at any div a copy from this div will be added to the
end (the fired div wont be clickable any more, and the new div will
be clickable). And so on…..</p>
<p>I have tried this but it creates two divs at the same time and the div can be clickable again .!!</p>
<pre><code>
<div id="parent" class="p">
<div class="red" class="d"></div>
<div class="green" class="d"></div>
<div class="blue" class="d"></div>

<p>I'm trying to type a higher order function. The basic idea is that high is passed a function fn, and it returns a function that takes the exact same parameters and gives the same return type.</p>
<p>It's an exercise in trying to understand the language better. I have something that works but erases the type from the input parameters. Please see the types Test1 vs Test2 below:</p>
<pre><code>export function high<R>(fn: (...args: any[]) => R) {
return (...args: any[]) => {
const moddedArgs = args.map((el) =>
typeof el === "string" ? el + "OMG" : el
);
return fn(...moddedArgs);
};
}
const test1 = (nr1: number, str1?: string) => (str1 ?? "Wow").repeat(nr1);
test1(3, "yo");
// returns yoyoyo
test1(3);
// returns WowWowWow
const test2 = high(test1);
test2(3, "yo");
// returns yoOMGyoOMGyoOMG
type Test1 = typeof test1;
// type Test1 = (nr1: number, str1?: string) => string
type Test2 = typeof test2;
// type Test2 = (...args: any[]) => string
</code></pre>

<p>I'm trying to create a function generator prints one element in the array targets at the specified time in milliseconds in the timeArray and after the value is printed out the list will go to the next element in the time array and targets array and after the next time interval in the timeArray we print out the next value in the target array and continute to follow the same pattern until we reach the end of the array</p>
<p>I tried using the code shown below but it only prints out the first 2 elements in the timeArray but it doesn't print all of the other elements but I'm not sure if it's printing them after the first two time intervals in timeArray</p>
<pre><code>let j = 0;
var timeArray = [6, 68, 51, 41, 94, 65, 47, 85, 76, 136];//Array that shows how long after each number printed to the console the next value should be printed
var targets = [9, 10, 8, 7, 9, 7, 7, 9, 9, 7];//Array of numbers that should be printed
let generator = generateSequence();
async function* generateSequence(casiInfluence){
yield new Promise((resolve, reject) => {
setTimeout(() => resolve(console.log(targetArray[j]), timeArray[j]);
console.log(timeArray[j]);
});
}
(async function main(){
for await(var result of generateSequence()){
console.log(result);
j++;
result = generator.next();
}
}());
</code></pre>

<p>I'm currently trying to code a simple game for class. Right now I want my rectangle to stay within the bounds of my canvas when i move it by using a bounce function, but it doesn't seem to be working and I cant figure out why. I have tried implementing my bounce function and calling it at the top. When I move my rectangle it goes past the bounds of the canvas without staying inside and "bouncing" off the border.</p>
<pre><code>var canvas;
var ctx;
var w = 1000;
var h = 700;
var o1 = {
x: 100,
y: h/2,
w: 100,
h: 100,
c: 0,
a: 100,
angle: 0, //changes angle that shape sits at
distance: 10
}
document.onkeydown = function(e){keypress(e, o1)}
setUpCanvas();
// circle (o1);
animationLoop();
function animationLoop(){
//clear
clear();
//draw
rect(o1);
//update
bounce(o1)
requestAnimationFrame(animationLoop)
}
function bounce(o){
if(o.x+o.w/2 > w || o.x-o.w/2 < 0){ //makes shape bounce from edge instead of middle. collision detection
o.changeX *= -1; //same as o.changeX = o.changeX = -1;
}
if(o.y+o.h/2 > h || o.y-o.h/2 <0){
o.changeY *= -1;
}
}
function updateData(o){
o.x += o.changeX;
o.y += o.changeY;
}
function keypress(e,o){
if (e.key == "ArrowUp"){
o.angle = 270;
o.distance= 80;
forward(o);
}
if (e.key == "ArrowDown"){
o.angle = 90;
o.distance= 20;
forward(o);
}
}
function forward(o){ //makes shape able to move
var cx;
var cy;
cx = o.distance*Math.cos(o.angle);
cy = o.distance*Math.sin(o.angle)
o.y += cy;
}
function rect(o){
var bufferx = o.x;
var buffery = o.y
o.x = o.x - o.w/2;
o.y = o.y- o.h/2;
ctx.beginPath(); //this is very important when we are changing certain ctx properties
ctx.moveTo(o.x,o.y);
ctx.lineTo(o.x+o.w,o.y);

<p>I have a string like this:<br />
<code>let string = "/gb/fr/firstPage/secondPage</code>.\</p>
<p>I want to compare the <code>/gb/fr/</code> part against an array like below:</p>
<p><code>let array = [ "/fr/fr", "/de/de", "/es/es","/ro/ro", "/it/it"]</code></p>
<p>and if its the same return the string, but if not the same return :</p>
<p><code>string = "/gb/en/firstPage/secondPage</code>\</p>
<p>Can you help me out please or explain how to do it ?</p>
<p>more example:</p>
<p><code>"/ee/et/firstPage/secondPage"</code></p>
<p>should return :</p>
<p><code>"/ee/en/firstPage/secondPage"` </code></p>
<p>another example :</p>
<p><code>"/lt/lt/firstPage/secondPage"</code></p>
<p>should return:</p>
<p><code>"/lt/en/firstPage/secondPage"</code></p>
<p>so it basically checks the first part <code>/fr/</code></p>
<p>if it exists it will return the corresponding link otherwise it will replace the second part with `/en/`</p>

<p>So I need to straight pivot my data with no aggregation. I have tried PIVOT, UNPIVOT, CROSS APPLY, and CASE statements all driving me crazy.</p>
<p>Here is my current data set</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Header</th>
<th>Contract Value</th>
<th>Total Cost</th>
<th>Profit</th>
</tr>
</thead>
<tbody>
<tr>
<td>Original Budget</td>
<td>1000</td>
<td>900</td>
<td>100</td>
</tr>
<tr>
<td>Change Orders</td>
<td>100</td>
<td>90</td>
<td>90</td>
</tr>
</tbody>
</table>
</div>
<p>And this is what I would like to do. I want the values in the rows to be the column names.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Header</th>
<th>Original Budget</th>
<th>Change Orders</th>
</tr>
</thead>
<tbody>
<tr>
<td>Contract Value</td>
<td>1000</td>
<td>100</td>
</tr>
<tr>
<td>Total Cost</td>
<td>900</td>
<td>100</td>
</tr>
<tr>
<td>Profit</td>
<td>100</td>
<td>10</td>
</tr>
</tbody>
</table>
</div>
<p>Can someone please point me in the right direction.</p>

<p>I am having a problem that I just don't know how to solve and nothing I'm finding is helping. My problem is that I have a list of names (strings), in this list I will have the same name show up more than once.</p>
<pre class="lang-py prettyprint-override"><code>lst = ['hello.com', 'hello.com', 'hello.com', 'world.com', 'test1.com']
index = web_lst.index(domain)+1
print(index)
</code></pre>
<blockquote>
<p>The issue with this code is that index() will always find and use the first 'hello.com' instead of any of the other "hello.com's", so index will always be 1. If I were asking for any of the other names then it'd work I think.</p>
</blockquote>
<p>I am trying to get the integer representation of the 'hello.com' names (1, 2, 3, etc.), and I don't know how to do that or what else to use besides python lists. This, I don't think is going to work and I'm asking for any other ideas on what to do or use instead of using a list. (if what I'm trying to do is not possible with lists)</p>
<br />
<br />
<p>My main goal is basically a login manager using sqlite3 and I want to have the ability to have multiple logins with some having the same domain name (but with different data and notes, etc.), because we like to have multiple logins/accounts for 1 website. I have a TUI (beaupy) for selecting the domain/option you want to get the login for but if you have more than 1 of the same domain name it doesn't know which one to pick. I have managed to use integers as IDs in the sqlite3 database to help but the main issue is the picking of an element from a list to get a number, to then plug into the read() function. So the list options will correlate to the "IDs" in the database. List index 0+1 would be option/row 1 in the database (and so on).</p>
<pre class="lang-py prettyprint-override"><code>def clear():
os.system('clear||cls')
def add(encrypted_data):
ID = 1
database = sqlite3.connect('vault.gter')
c = database.cursor()
#Check to see if IDs exist and if yes then get how many/length of list and add 1 and use that instead.
c.execute("SELECT id FROM logins")
all_ids = c.fetchall()
out = list(itertools.chain(*all_ids))
list_length = len(out)
if not all_ids:
pass
else:
for x in out:
if x == list_length:
ID = x+1
else:
pass
c.execute(f"INSERT INTO logins VALUES ('{ID}', '{encrypted_data}')")
database.commit()
database.close()
def domains(dKey):
database = sqlite3.connect('vault.gter')
c = database.cursor()
c.execute("SELECT data FROM logins")
websites = c.fetchall()
enc_output = list(itertools.chain(*websites))
web_lst = []
note_lst = []
for x in enc_output:
result = gcm.stringD(x, dKey) #decrypt encrypted json string.
obj_result = json.loads(result) #turns back into json object
website = obj_result['Domain']
notes = obj_result['Notes']
web_lst.append(website)
note_lst.append(notes)
for w,n in zip(web_lst, note_lst):
with open('.lst', 'a') as fa:
fa.writelines(f"{w} ({n})\n")
fa.close()
with open(".lst", "r+") as fr:
data = fr.read()
fnlst = data.strip().split('\n')
fr.truncate(0)
fr.close()
os.remove(".lst")
print(f'(Press "ctrl+c" to exit)\n-----------------------------------------------------------\n\nWebsite domain/name to get login for?\n')
domain = beaupy.select(fnlst, cursor_style="#ffa533")
clear()
if domain == None:
clear()
return
else:
domain = domain.split(' ', 1)[0] #get first word in a string.
print(domain) #debug
index = web_lst.index(domain)+1
input(index) #debug
pwd = read(index)
return pwd
# Come up with new way to show available options to chose from and then get number from that to use here for "db_row".
def read(db_row):
database = sqlite3.connect('vault.gter')
c = database.cursor()
c.execute("SELECT id FROM logins")
all_ids = c.fetchall()
lst_output = list(itertools.chain(*all_ids))
if not all_ids:
input("No IDS") #debug
database.commit()
database.close()
return
else:
for x in lst_output:
if x == db_row:
c.execute(f"SELECT data FROM logins WHERE id LIKE '{db_row}'") #to prevent my main issue of it not knowing what I want when two domain names are the same.
stoof = c.fetchone()
database.commit()
database.close()
return stoof[0]
else:
#(debug) - input(f"error, x is not the same as db_row. x = {x} & db_row = {db_row}")
pass
</code></pre>
<br />
<br />
<p>If anyone has a better way of doing this whole login manager thing, I'll be very very appreciative. From handling the database and sqlite3 commands, better IDs? to perhaps completely a different (and free) way of storage. And finding a better way to handle my main problem here (with or without having to use lists). Anything is helpful. <3</p>
<blockquote>
<p>If anyone has questions then feel free to ask away and I'll respond when I can with the best of my knowledge.</p>

<p>In many Prolog guides the following code is used to illustrate "negation by failure" in Prolog.</p>
<pre><code>not(Goal) :- call(Goal), !, fail.
not(Goal).
</code></pre>
<p>However, those same tutorials and texts warn that this is not "logical negation".</p>
<p><strong>Question:</strong> What is the difference?</p>
<p>I have tried to read those texts further, but they don't elaborate on the difference.</p>

<p>I have 3 dataframes with the same dimensions. I want to create a dataframe with min value from each element in 3 dataframes. Is there a more efficient way than running loop on cloumn and then row going through each element one by one?</p>
<pre><code>Dataframe X
| Column A | Column B |
| -------- | -------- |
| Cell X1 | Cell X2 |
| Cell X3 | Cell X4 |
Dataframe Y
| Column A | Column B |
| -------- | -------- |
| Cell Y1 | Cell Y2 |
| Cell Y3 | Cell Y4 |
Dataframe Z
| Column A | Column B |
| -------- | -------- |
| Cell Z1 | Cell Z2 |
| Cell Z3 | Cell Z4 |
</code></pre>
<pre><code>Dataframe Target Output
| Column A | Column B |
| -------- | -------- |
| Min (Cell X1,Y1,Z1) | Min (Cell X2,Y2,Z2) |
| Min (Cell X3,Y3,Z3) | Min (Cell X4,Y4,Z4) |
</code></pre>
<p>Thank you!</p>
<p>I tried simple loop for each column and then each row
for (c in 1:3){
for (r in 1:2){
........
}
}</p>

<p>I'm designing a Neocities site and on one of my pages the background image isn't showing up. I've tried doing it in HTML and CSS but neither will work.</p>
<p>[This] (<a href="https://maggssszzz.neocities.org/spitbucket.html" rel="nofollow noreferrer">https://maggssszzz.neocities.org/spitbucket.html</a>) is the page in question and <a href="https://www.google.com/url?sa=i&url=https%3A%2F%2Fpngtree.com%2Ffree-backgrounds-photos%2Fabstract-lines&psig=AOvVaw0DqRellrv87omUXChv5XUF&ust=1670010209669000&source=images&cd=vfe&ved=0CA8QjRxqFwoTCOia0u2x2fsCFQAAAAAdAAAAABAU" rel="nofollow noreferrer">this</a> is the image I'm trying to attach.</p>
<p>I initially tried placing it in the head of my HTML like this:</p>
<pre><code><style>
background-image: "url(https://www.google.com/url?sa=i&url=https%3A%2F%2Fpngtree.com%2Ffree-backgrounds-photos%2Fabstract-lines&psig=AOvVaw0DqRellrv87omUXChv5XUF&ust=1670010209669000&source=images&cd=vfe&ved=0CA8QjRxqFwoTCOia0u2x2fsCFQAAAAAdAAAAABAU)";
</style>
</code></pre>
<p>But that didn't do anything, so then I thought about putting it in CSS. I tried this 2 different ways and neither worked:</p>
<pre><code>.body {
text-align: center;
background-image: url(https://us.123rf.com/450wm/leavector/leavector1901/leavector190100001/leavector190100001.jpg?ver=6);
}
.square {
text-align: center;
background-color: #16a868;
line-height: 70px;
width: 400px;
height: 800px;
color: #701ba1;
margin: 20px auto;
}
</code></pre>
<p>and attempt 2:</p>
<pre><code>.body {
text-align: center;
}
.square {
text-align: center;
background-color: #16a868;
background-image: url(https://us.123rf.com/450wm/leavector/leavector1901/leavector190100001/leavector190100001.jpg?ver=6);
line-height: 70px;
width: 400px;
height: 800px;
color: #701ba1;
margin: 20px auto;
}
</code></pre>
<p>But nothing works. What did I do wrong?</p>

<p>I'd like the TypeScript compiler to infer the names of properties on an object so that it's easier to invoke the appropriate functions later. However, despite considering invoking functions, TypeScript doesn't give any intellisense of the functions I can invoke.</p>
<p>Taking into account the following example:</p>
<pre class="lang-js prettyprint-override"><code>interface InputBase {
alias: string;
}
const input: Array<InputBase> = [
{ alias: 'getNotes' },
{ alias: 'getComments' },
];
const client = input.reduce((acc, curr: InputBase) => {
return {
...acc,
[curr.alias]: () => {
return curr.alias + ' call';
},
};
}, {});
client.getNotes();
</code></pre>
<p>My problem is really the lack of inference in the client variable, because currently the data type is <code>{}</code> despite appearing in the terminal <code>{getNotes: ƒ, getComments: ƒ}</code>.</p>
<p>How can I resolve this?</p>

<p>Alternatively, I manually run in anaconda prompt and the code works.</p>
<p><code>"C:xxx.exe" "C:xxx.py"</code></p>
<p>What I observed on screen was the black cmd window pop out and disappeared in second. It did not work as expected. Is there anything I input incorrectly?</p>

<p>Inside my service I have a post method in which return type is IInfluencerRewardSetup</p>
<pre><code>influencerRewardSetup(payload: IInfluencerRewardSetup): Observable<IInfluencerRewardSetup> {
return this.httpClient.post<IInfluencerRewardSetup>(this.baseUrl, payload)
.pipe(retry(1),
this.errorHandler());
}
</code></pre>
<p>and</p>
<pre><code>private errorHandler() {
return catchError(err => {
this.notificationService.error(err.message, '');
throw new Error(err.message || 'Server error');
});
}
</code></pre>
<p>But the problem is I am having this type of error:</p>
<pre><code>Type 'Observable<unknown>' is not assignable to type 'Observable<IInfluencerRewardSetup>'
</code></pre>
<p>Please note that, errorHandler will handle other HTTP calls as well.
Why am I having this error and how can I fix that type of issue here? can someone please help?</p>

<p>And I only want to extract the values:</p>
<pre><code>20750
20751
20752

<p>From the file.</p>
<p>The closest I got to was:</p>

<p>But this extracts:</p>
<pre><code>data: 20751
data:

<p>I want digits only.</p>
<p>How do I do this?</p>

<p>-----<strong><strong>START EDIT</strong></strong>-----</p>
<p>I don't know what I was doing wrong before, but the code below was somehow not working for me, and now is working, and it's exactly the same. I don't know how or what I was missing before, but both this minimal example and the real project I am working on is working now. Obviously I changed something, but I can't figure out what. I just know it's working now. Sorry for the confusion and thanks to everyone for helping.</p>
<p>-----<strong><strong>END EDIT</strong></strong>-----</p>
<p>I am new to Solidity and am using the <code>Factory</code> pattern for deploying a contract from another contract. I am trying to get the contract address of the deployed contract, but I am running into errors.</p>
<p>I already tried the solution in <a href="https://stackoverflow.com/questions/42230532/getting-the-address-of-a-contract-deployed-by-another-contract">this question</a>, but I'm getting the following error: <code>Return argument type struct StorageFactory.ContractData storage ref is not implicitly convertible to expected type (type of first return variable) address.</code></p>
<p>Here is my code:</p>
<pre><code>// START EDIT (adding version)
pragma solidity ^0.8.0;
// END EDIT
contract StorageFactory {
struct ContractData {
address contractAddress; // I want to save the deployed contract address in a mapping that includes this struct
bool exists;
}
// mapping from address of user who deployed new Storage contract => ContractData struct (which includes the contract address)
mapping(address => ContractData) public userAddressToStruct;
function createStorageContract(address _userAddress) public {
// require that the user has not previously deployed a storage contract
require(!userAddressToStruct[_userAddress].exists, "Account already exists");
// TRYING TO GET THE ADDRESS OF THE NEWLY CREATED CONTRACT HERE, BUT GETTING AN ERROR
address contractAddress = address(new StorageContract(_userAddress));
// trying to save the contractAddress here but unable to isolate the contract address
userAddressToStruct[_userAddress].contractAddress = contractAddress;
userAddressToStruct[_userAddress].exists = true;
}
}
// arbitrary StorageContract being deployed
contract StorageContract {
address immutable deployedBy;
constructor(address _deployedBy) {
deployedBy = _deployedBy;
}
}
</code></pre>
<p>How can I get this contract address, so I can store it in the <code>ContractData</code> struct? Thanks.</p>

<p>How can I do to type something in the field of the image below?</p>
<p>I've tried without success:</p>
<pre><code>from threading import local
import pandas as pd
import pyautogui
from time import sleep
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
</code></pre>
<p><code>wait.until(EC.presence_of_element_located((By.XPATH,"//input[@type='file']"))send_keys("C:/Users/my_user/Downloads/doch.jpeg")</code></p>
<pre><code>for index, row in df.iterrows():
actions.send_keys((row["message"]))
actions.perform()
</code></pre>
<p>The only palliative solution was:</p>
<pre><code>pyautogui.write((row["photo"]))
pyautogui.press("enter")
</code></pre>
<p>I don't want to use pyautogui as it uses the keyboard command and I can't do anything on the computer while the code is running.</p>

<p>am using opensearch 2.4 and I have an index with some fields while creating , later i started saving new field to the index , now when i query on the newly created field am not getting any results</p>
<p>ex : query 1
POST abc/_search</p>
<pre><code>{
"query": {
"bool": {
"must": [
{
"terms": {
"name": [
"john"
]
}
}
]
}
}
}
</code></pre>
<p>above works fine because name fields exists since creation of index</p>
<p>query 2 :
POST abc/_search</p>
<pre><code>{
"query": {
"bool": {
"must": [
{
"terms": {
"lastname": [
"William"
]
}
}
]
}
}
}
</code></pre>
<p>above query doesnt work though i have some documents with lastname william</p>

<p>For the final input, your program prompts the user for their year of study. Once again, this is not a
required field, that is, a default value of 1 (as in 1st year of study) should be submitted if the user chooses
to leave this field blank. Additionally, you must validate the data the user provides (if provided) to ensure
that it is not less than 1, and not greater than 3 (valid range is 1-3 years of study).</p>
<p>If your solution detects invalid input, your program must loop to allow the user to re-enter year of study,
this process continues indefinitely, until valid input is detected.</p>
<hr />
<p>I have tried a few different methods and this is my most recent attempt, but after 5 hours, I needed to ask for help. Code is below ( Yes, I'm a noob :( )</p>
<pre><code>do {
var yearofStudy = prompt("Please enter your Year of Study", "1")
console.log(yearofStudy)
}
while
( yearofStudy > 1 && yearofStudy <4 )
</code></pre>

<p>I have a byte array that I made, and I am writing it to a json file. This works, but I want to have a formatted JSON file instead of a massive wall of text.</p>
<p>I have tried decoding the byte array with utf-8, but instead I get <code>UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte</code>. My plan was to then take this string and use json.dumps() to format it.</p>
<p>Trying json.dumps() without any other formatting gives this: <code>TypeError: Object of type bytearray is not JSON serializable</code></p>
<pre><code>content = bytearray()
content_idx = 0
try:
with open(arguments.input_file, 'rb') as input_file:
while (byte:=input_file.read(1)):
content += bytes([ord(byte) ^ xor_key[content_idx % (len(xor_key))]])
content_idx += 1
except (IOError, OSError) as exception:
print('Error: could not read input file')
exit()
try:
with open(arguments.output_file, 'wb') as output_file:
output_file.write(json.dumps(content.decode('utf-8'), indent=4))
except (IOError, OSError) as exception:
print('Error: could not create output file')
exit()

As we all know, when the url doesn't match any endpoints, the server will automatically return 404 code.</p>
<p>Now that I want the service to record these requests into a log, so I want to set a default handler for them.<br />
Is it possible? How?</p>

<p>I'd like to try to eliminate bounds checking on code generated by Rust. I have variables that are rarely zero and my code paths ensure they do not run into trouble. But because they can be, I cannot use <code>NonZeroU64</code>. When I am sure they are non-zero, how can I signal this to the compiler?</p>
<p>For example, if I have the <a href="https://play.rust-lang.org/?version=stable&mode=release&edition=2021&gist=ebdd2e76b5e4ddd7e515cb49be3995f2" rel="nofollow noreferrer">following function</a>, I know it will be non-zero. Can I tell the compiler this or do I have to have the unnecessary check?</p>
<pre><code>pub fn f(n:u64) -> u32 {
n.trailing_zeros()
}
</code></pre>
<p>I can wrap the number in <code>NonZeroU64</code> when I am sure, but then I've already incurred the check, which defeats the purpose ...</p>

<p>How would I go about making a countdown clock using only HTML and JS? Problem is, there are a few features that are required:
• It must reset on a page reload
• It must count down from a certain number of hours <strong>from page load</strong> (i.e. not a universal time)</p>
<p>I realize these are a lot of demands, but anything hints/tips/advice will help. Thanks in advance :]</p>
<p>I've tried some online timers, but they are universal and don't reset on a page reload.</p>

<p>i have a problem which i am trying to solve and cant for the life of me figure it out. I feel like its the simplest answer but yet i'm still stuck.</p>
<p>The instructions stated that the application must do the following:
Ask the user to input the marks for the five subjects in a list/array.
The program must ensure that the marks are between 0 and 100
Display the list/array of marks entered.
Find the sum of all the marks in the list (all five subjects) and display the output as:
The sum of your marks is: [sum]
Find the average of all the marks in the list (all five subjects) and display the output as:
The average of your marks is: [average mark]</p>
<p>this is what i have tried</p>
<pre><code>print("please enter your 5 marks below")
# read 5 inputs
mark1 = int(input("enter mark 1: "))
if mark1 <= 0 or mark1 <= 100:
print("Mark is acceptable")
else:
print("Mark is not acceptable")
mark1 = int(input("enter mark 1: "))
mark2 = int(input("enter mark 2: "))
if mark2 <= 0 or mark2 <= 100:
print("Mark is acceptable")
else:
print("Mark is not acceptable")
mark2 = int(input("enter mark 2: "))
mark3 = int(input("enter mark 3: "))
if mark3 <= 0 or mark3 <= 100:
print("Mark is acceptable")
else:
print("Mark is not acceptable")
mark3 = int(input("enter mark 3: "))
mark4 = int(input("enter mark 4: "))
if mark4 <= 0 or mark4 <= 100:
print("Mark is acceptable")
else:
print("Mark is not acceptable")
mark4 = int(input("enter mark 4: "))
mark5 = int(input("enter mark 5: "))
if mark5 <= 0 or mark5 <= 100:
print("Mark is acceptable")
# create array/list with five marks
marksList = [mark1, mark2, mark3, mark4, mark5]
# print the array/list
print(marksList)
# calculate the sum and average
sumOfMarks = sum(marksList)
averageOfMarks = sum(marksList) / 5
# display results
print("The sum of your marks is: " + str(sumOfMarks))
print("The average of your marks is: " + str(averageOfMarks))

<p>I'm having a hard time figuring out how to pass a function's return as a parameter to another function. I've searched a lot of threads that are deviations of this problem but I can't think of a solution from them. My code isn't good yet, but I just need help on the line where the error is occurring to start with.</p>
<p>Instructions:</p>
<ul>
<li>create a function that asks the user to enter their birthday and returns a date object. Validate user input as well. This function must NOT take any parameters.</li>
<li>create another function that takes the date object as a parameter. Calculate the age of the user using their birth year and the current year.</li>
</ul>
<pre><code>def func1():
bd = input("When is your birthday? ")
try:
dt.datetime.strptime(bd, "%m/%d/%Y")
except ValueError as e:
print("There is a ValueError. Please format as MM/DD/YYY")
except Exception as e:
print(e)
return bd
def func2(bd):
today = dt.datetime.today()
age = today.year - bd.year
return age
</code></pre>
<p>This is the Error I get:</p>
<pre><code>TypeError: func2() missing 1 required positional argument: 'bday'
</code></pre>
<p>So far, I've tried:</p>
<ul>
<li>assigning the func1 to a variable and passing the variable as func2 parameter</li>
<li>calling func1 inside func2</li>
<li>defining func1 inside func2</li>
</ul>

<p>In this case, the "all_lines" variable is initalised in the context manager, and it is accessible from the function "part_1".</p>
<pre><code>total = 0
with open("advent_input.txt", "r") as txt:
all_lines = []
context_total = 0
for line in txt:
all_lines.append((line.rstrip().split(" ")))
def part_1():
# total = 0
for line in all_lines:
if line[0] == "A":
if line[1] == "Y":
total += 8
elif line[1] == "X":
context_total += 4
</code></pre>
<p>However, "context_total", which is also initalised in the context manager, does not work in the function "part_1". And "total" from the global scope does not work either. How come "all_lines" works?</p>

<p>I'm getting the error</p>
<blockquote>
<p>CS0426 "the type name 'GetRequest' does not exist in the type 'Request'</p>
</blockquote>
<p>when I'm quite sure that it does. I don't understand what I possibly did wrong here. Here's the code I'm working with:</p>
<pre><code>public class Request
{
public static Request GetRequest()
{
return null;
}
}
</code></pre>
<p>In this class you can clearly see that <code>GetRequest</code> does infact exist within the type 'Request'. However when I try and use this method I get an error saying that it doesn't exist.</p>
<p>This line generates the error I have been getting:</p>
<pre><code>Request req = new Request.GetRequest();
</code></pre>

<p>Is there a way to continue a function based on where it was last run.</p>
<p>We want each call to do something else, e.g. (first call adds 1, second adds 2, third call adds 3), and then do something else.</p>

<p>Currently I was trying to do a machine learning classification of 6 time series datasets (in .csv format) using MiniRocket, an sktime machine learning package. However, when I imported the .csv files using pd.read_csv and run them through MiniRocket, the error "TypeError: X must be in an sktime compatible format" pops up, and it says that the following data types are sktime compatible:
['pd.Series', 'pd.DataFrame', 'np.ndarray', 'nested_univ', 'numpy3D', 'pd-multiindex', 'df-list', 'pd_multiindex_hier']
Then I checked the data type of my imported .csv files and got "pandas.core.Frame.DataFrame", which is a data type that I never saw before and is obviously different from the sktime compatible pd.DataFrame. What is the difference between pandas.core.Frame.DataFrame and pd.DataFrame, and how to convert pandas.core.Frame.DataFrame to the sktime compatible pd.DataFrame?</p>
<p>I tried to convert pandas.core.Frame.DataFrame to pd.DataFrame using df.join and df.pop functions, but neither of them was able to convert my data from pandas.core.Frame.DataFrame to pd.DataFrame (after conversion I checked the type again and it is still the same).</p>

<p>I just want to have a simple React app, where you can add a circle on button click, remove the last drawn circle, and remove all drawn circles... Ive tried to do this with canvas before. I could draw circles on click but had Problems removing them, so I have asked in a Discord where they explained me that you need to clear and redraw the canvas every time you want to remove an element and that its easier to work with svgs, so I've set the thing up with svgs but now its not even working with the add function...</p>
<p>Thx for help !!</p>

digits = int(math.log10(num))+1
print (digits)

<p>I get the error 'ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().'
I am not sure what the problem is. Any help or advice is appreciated -- I am just starting.</p>
<p>I expected the output to be 'yes' from the loop. But I just got the 'ValueError' message. But, when I run the condition by itself, the output is 'True' so I'm not sure what is wrong.</p>

<p>I need to track how long many processes take and so my code looks like this:</p>
<pre><code>console.log("Doing thing 1");
var startTime = performance.now();
var thing = doThing()
times.loadTime = performance.now() - startTime;
console.log("Doing thing 2");
startTime = performance.now();
var thing2 = doOtherThing();
var endTime = performance.now();
times.thingTime2 = endTime - startTime;
console.log("Doing thing 3");
var thing3 = doThing3();
ties.thingTime3 = performance.now() - endTime;
</code></pre>
<p>As you can guess, this is getting hard to read.</p>
<p>I know that in my current environment I can use things like:</p>
<pre><code>console.startTime();
console.startTime("Thing 1");
console.endTime();
</code></pre>
<p>And so on. See the <a href="https://developer.mozilla.org/en-US/docs/Web/API/console" rel="nofollow noreferrer">console</a> object.</p>
<p>But I think I've seen something where javascript code was using blocks or labels like this:</p>
<pre><code>thing1 {
var thing = doThing()
}
thing2 {
var thing2 = doOtherThing();
}
thing3 {
var thing3 = doThing3();
}
// desired result { name: "thing1", startTime: 0, endTime: 10 }
console.log(thing1);
</code></pre>
<p>Or labels:</p>
<pre><code>thing1:
var thing = doThing()
end
</code></pre>
<p>These look much more readable to me.</p>
<p>Is there a way to do this in JavaScript?</p>

<p>I am trying to remove all characters that are not digit, dot (.), plus/minus sign (+/-) with empty character/string for float conversion.<br>
When I pass my string through regex_replace function I am returned an empty string.<br>
I belive something is wrong with my regex expression <code>std::regex reg_exp("\\D|[^+-.]")</code><br><br>
Code</p>
<pre><code>#include <iostream>
#include <regex>
int main()
{
std::string temporary_recieve_data = " S S +456.789 tg\r\n";
std::string::size_type sz;
const std::regex reg_exp("\\D|[^+-.]"); // matches not digit, decimal point (.), plus sign, minus sign
std::string numeric_string = std::regex_replace(temporary_recieve_data, reg_exp, ""); //replace the character that are not digit, dot (.), plus-minus sign (+,-) with empty character/string for float conversion
std::cout << "Numeric String : " << numeric_string << std::endl;
if (numeric_string.empty())
{
return 0;
}
float data_value = std::stof(numeric_string, &sz);
std::cout << "Float Value : " << data_value << std::endl;
return 0;
}
</code></pre>
<hr />
<p>I have been trying to evaluate my regex expression on regex101.com for past 2 days but I am unable to figure out where I am wrong with my regular expression. When I just put \D, the editor substitutes non-digit character properly but soon as I add or condition <code>|</code> for not dot <code>.</code> or plus <code>+</code> or minus <code>-</code> sign the editor returns empty string.</p>

<p>This is more a design question so please bear with me.</p>
<p>I have a system that stores locations consisting of the ID, Longitude and Latitude.</p>
<p>I need to compare the distance between my current location and the locations in the database a only choose ones that are within a certain distance.</p>
<p>I have the formula that calculates the distance between 2 locations based on the long/lat and that works great.</p>
<p>My issue is I may have 10 of thousands of locations in the database and don't want to loop through them all every time I need a list of locations close by.</p>
<p>Not sure what other datapoint I can store with the location to make it so I only have to compare a smaller subset.</p>
<p>Thanks.</p>

<p>To get the minimum value in an array, I made the method minValue</p>
<pre class="lang-java prettyprint-override"><code>public int minValue() {
int smallestVal = 0; //field
if (intArray.length == 0) { //if array is empty, return 0
return 0;
}
int a = intArray[0]; //field
for (int i : intArray) {
if (i > a) {
smallestVal = a;
}
else {
a = i;
}
}
return smallestVal; //returns the smallest value
}
</code></pre>
<p>Tested it in a main method with <code>arr9 = { 1, 2, -1, 40, 1, 40, 0, 0, -3, 2, 2, -2, -5, 0, 1, -4, -5 }</code>
and <code>arr10 = { 4, 5, 5, 4, 1, 5, -3, 4, -1, -2, -2, -2, -2, -2, -2, 1, 4, 5, -5 }</code></p>
<p>For arr9, it returns -5 but for arr10 it returns -3 instead of -5.
Is there something I need to change in my code?</p>

<p>I am using <code>flask</code> and <code>flask-restx</code> try to create a protocol to get a specific string from another service. I am wonder if there is a way I can pass the parameter from another function to server side.
For example, here's my server side:</p>
<pre><code>from flask_restx import Api,fields,Resource
from flask import Flask
app = Flask(__name__)
api = Api(app)
parent = api.model('Parent', {
'name': fields.String(get_answer(a,b)),
'class': fields.String(discriminator=True)
})
@api.route('/language')
class Language(Resource):
# @api.marshal_with(data_stream_request)
@api.marshal_with(parent)
@api.response(403, "Unauthorized")
def get(self):
return {"happy": "good"}
</code></pre>
<p>get_answer function in a different file:</p>
<pre><code>get_answer(a,b):
return a + b
</code></pre>
<p>What I expect is to get the result of <code>get_answer</code> from a file, and then my API is generated so that the GET request can get it. I know that if there is a web page, we can use <code>render_template(</code> or <code>form</code> to get it. But what if I want to get the value from another function? I know we only run the server with <code>app.run()</code>, but are we able to pass any value into the server? Guessing <code>app.run(a,b)</code> should not work in this case. We definite need to pass two parameter into the server. Or we can store the answer of <code>get_answer(a,b)</code> in main with specific value of <code>a</code> and <code>b</code>, then pass the number into the server side. But it will need the parameter either way.</p>
<hr />
<p>One thing I've tested is wrapping up the server into a function. But in our case, is it a good idea to wrap a class inside a function as we have <code>class Language(Resource):</code>?</p>

<p>I have a checkout cart where you have different cart items, and for each one you can change the quantity prior to purchase.</p>
<p>Here's how the code looks:</p>
<pre><code>import React, { useEffect, useState } from "react";
import PureInput from "./PureInput";
import { useForm, Controller } from "react-hook-form";
const CartInner = React.forwardRef(
(
{
control,
element,
value,
handleOnChange,
images,
name,
monthlyAmount,
price,
projectedGrowth,
id,
...inputProps
}: any,
ref: any
) => {
return (
<div className="grid gap-8 grid-cols-2 mb-12 py-6 px-8 border-2 border-slate-200">
<div>
<PureInput
min={200}
max={price}
onChange={handleOnChange}
type="number"
step={200}
defaultValue={element.price}
id={id}
ref={ref}
{...inputProps}
/>
</div>
</div>
);
}
);
export default function Checkout() {
const { control, handleSubmit } = useForm();
const handleOnChange = (index: any, e: any) => {
console.log(e, "e");
};
const onSubmit = async (data: any) => {
console.log(data, "data from Form.tsx");
};
return (
<form onSubmit={handleSubmit(onSubmit)} className="grid gap-8 grid-cols-3">
<div className="col-span-2">
{[0, 2].map((element, index) => {
return (
<fieldset key={index}>
<Controller
render={({ field }) => (
<CartInner
element={element}
handleOnChange={(e) => handleOnChange(index, e)}
{...field}
/>
)}
name={`test.${index}.lastName`}
control={control}
/>
</fieldset>
);
})}
<button>Progess to payment</button>
</div>
</form>
);
}
</code></pre>
<p>And the PureInput:</p>
<pre><code>import * as React from "react";
type IProps = any;
const PureInput = React.forwardRef(
({ className, id, onChange, ...inputProps }: IProps, ref: any) => {
return (
<input
id={id}
ref={ref}
onChange={onChange}
type="input"
className={`${className} block w-full bg-white text-black rounded-md border-2 font-bold border-grey-200 text-xl px-4 py-4 focus:border-orange-500 focus:ring-orange-500`}
{...inputProps}
/>
);
}
);
export default PureInput;
</code></pre>
<p>Everything works fine in terms of submitting the form. When I do, I get an array of whatever values I have entered into the input:</p>
<pre><code>[{lastName: "1600"}
{lastName: "800"}]
</code></pre>
<p>My package versions:</p>
<pre><code>"react-dom": "18.2.0",
"react-hook-form": "^7.29.0",
</code></pre>
<p>But my onChange no longer fires. How can I get the onChange to fire so I can log the value of the input inside <code><Checkout /></code> component?</p>
<p>Here's a <a href="https://codesandbox.io/s/realestateinvestmentcalculator-styling-y4jm9b?file=/src/PureInput.tsx:0-538" rel="nofollow noreferrer">codesandbox</a> if it helps</p>

<p>i created a file with the colors that i want to use in my project, but when i try to used, flutter does not acept the variables as a correct color.</p>
<p>This is the colors file:</p>
<pre><code>import 'package:flutter/material.dart';
class ColorSkh {
static Color innovation = const Color.fromARGB(255, 59, 18, 45);
static Color fresh = const Color.fromARGB(255, 172, 155, 163);
static Color hightech = const Color.fromARGB(255, 0, 128, 157);
static Color sophisticated = const Color.fromARGB(255, 230, 231, 232);
static Color sk = const Color.fromARGB(255, 191, 205, 217);
static Color white = const Color.fromARGB(255, 255, 255, 255);
}
</code></pre>
<p>And this is how i am using it</p>
<pre><code>
import 'package:analytic_skh/ui/color_skh.dart';
.
.
.
SizedBox(
*height: height * 0.10,
child: Align(
alignment: Alignment.centerLeft,
child: ElevatedButton.icon(
onPressed: onPressed,
icon: const Icon(Icons.settings),
label: const Text('Settings',
style:
TextStyle(backgroundColor: ColorSkh.innovation)),
style: ElevatedButton.styleFrom(
backgroundColor: Colors.white,
),
)),
)*
</code></pre>
<p>but i get the error that this is a invalid constant</p>

<p>I want to change the color of recyclervView item that I clicked(so user can understand that already checked the detail of the item) and go detail fragment page. However this background color change must be permanent should I store it in livedata of recycler view items. I share my codes at the end I am new to android programming so please explain your solution for beginner and my english level is not good. Thanks for everything.</p>
<pre><code>class AdapterRecycler() :
RecyclerView.Adapter<AdapterRecycler.ViewHolder>()
class ViewHolder(view: View, listener: onItemClickListener) : RecyclerView.ViewHolder(view) {
val name: TextView = view.findViewById(R.id.gameId)
val score: TextView = view.findViewById(R.id.scoreId)
val genre: TextView = view.findViewById(R.id.genres)
val layout1: RelativeLayout = view.findViewById(R.id.rowlayout)
init {
// Define click listener for the ViewHolder's View.
//val textView : TextView = view.findViewById(R.id.gameId)
itemView.setOnClickListener {
layout1.setBackgroundColor(Color.rgb(224,224,224))
listener.onItemClick(adapterPosition)
}
}
}
// Create new views (invoked by the layout manager)
override fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int): ViewHolder {
// Create a new view, which defines the UI of the list item
val view = LayoutInflater.from(viewGroup.context)
.inflate(R.layout.text_row_item, viewGroup, false)
return ViewHolder(view, listenerItems)
}
</code></pre>
<pre><code>class Games : Fragment() {
...
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
...
adapter.setOnItemClickListener(object : AdapterRecycler.onItemClickListener {
override fun onItemClick(position: Int) {
// Fragment transaction to detail page
requireActivity().supportFragmentManager.beginTransaction()
.replace(R.id.fragmentContainerView2, Details()).commit()
}
})
}
</code></pre>
<p>Should I store a boolean value in here to save item checked status?</p>
<pre><code>
data class Game(val name : String, val score : Int, val genres : Array<String>)
</code></pre>
<p>I tried solution at my codes and I get transaction but not the color changes of item layout.</p>

<p>I have a form that I created to make my work easier and recently figured out how to make certain fields automatically generate a comma and separates after 5 letters or numbers have been typed into it (CPT codes for medical claims that I have to look up) using the same coding you would for putting spaces between numbers. I also have coding here that would force letters to be capitalized since I'm a bit OCD about that stuff for work:</p>
<pre><code><input name="checkbox24" type="checkbox" id="checkbox24" onClick="FillDetails24(this.form);" /><span style="background-color:yellow">CPT</span>
<input type = "text" size="8" class = "uc-text-smooth" name="textfield24" id="textfield24" />
<script language = "JavaScript">
const forceKeyPressUppercase = (e) => {
let el = e.target;
let charInput = e.keyCode;
if((charInput >=97) && (charInput <= 122)) { // lowercase
if(!e.ctrlKey && !e.metaKey && !e.altKey) { // no modifier key
let newChar = charInput - 32;
let start = el.selectionStart;
let end = el.selectionEnd;
el.value = el.value.substring(0, start) + String.fromCharCode(newChar) + el.value.substring(end);
el.setSelectionRange(start+1, start+1);
e.preventDefault();
}
}
};
document.querySelectorAll(".uc-text-smooth").forEach(function(current) {
current.addEventListener("keypress", forceKeyPressUppercase);
});
document.getElementById('textfield24').addEventListener('input', function (g) {
g.target.value = g.target.value.replace(/[^\dA-Z]/g, '').replace(/(.{5})/g, '$1, ').trim();
});
</script>
</code></pre>
<p>When I use the checkbox, it automatically generates pre-written text using the following JavaScript:</p>
<pre><code>function FillDetails24(f) {
const elem = f.Reason;
const x = f.Action;
const y = f.Resolution;
f.Reason.value += ("Verify CPT " + f.textfield24.value + ". " + '\n');
f.Action.value += ("Adv on how to locate and use CPT lookup tool on plan website. Information provided in resolution. " + '\n');
f.Resolution.value += ("Adv on how to locate and use CPT lookup tool on plan website. Caller is looking to verify CPT " + f.textfield24.value + ". " + '\n' + '\n' );
}
</code></pre>
<p>However, because of the way that I put it together, the end result would be, "Adv on how to locate and use CPT lookup tool on plan website. Caller is looking to verify CPT V2020, 99213,. " The extra comma at the end is driving me nuts.</p>
<p>Since it was my first time using this</p>
<pre><code> document.getElementById('textfield24').addEventListener('input', function (g) {
g.target.value = g.target.value.replace(/[^\dA-Z]/g, '').replace(/(.{5})/g, '$1, ').trim();
});
</code></pre>
<p>with this</p>
<pre><code>function FillDetails24(f) {
const elem = f.Reason;
const x = f.Action;
const y = f.Resolution;
f.Reason.value += ("Verify CPT " + f.textfield24.value + ". " + '\n');
f.Action.value += ("Adv on how to locate and use CPT lookup tool on plan website. Information provided in resolution. " + '\n');
f.Resolution.value += ("Adv on how to locate and use CPT lookup tool on plan website. Caller is looking to verify CPT " + f.textfield24.value + ". " + '\n' + '\n' );
}
</code></pre>
<p>I'm not certain how I can code it to eliminate the last comma generated at the end when it pulls the value of textfield24.</p>
<p>This is a very long, complex html form I've coded by hand for fun and for personal use at work for 4 years with only a couple years of HTML training and a little bit of JavaScript I learned in high school forever ago and I've been busting my butt to make this work perfectly so that I only have to tweak the pre-written stuff when things change at work.</p>
<p>I'm at a loss on how to continue. Any suggestions?</p>

<p>I'm trying to avoid the extremely verbose hash maps and arrays, as commonly used in powershell. Why? Because I have 100's of lines, and it just doesn't make any sense to have to wrap every single line in a <code>@(name='foo; id='bar')</code> etc.), when all I need is a CSV type of array.</p>
<pre><code>$header = @('name', 'id', 'type', 'loc')
$mycsv = @(
# name, id, type, loc
'Brave', 'Brave.Brave', 1, 'winget'
'Adobe Acrobat (64-bit)', '{AC76BA86-1033-1033-7760-BC15014EA700}', 2, ''
'GitHub CLI', 'GitHub.cli', 3, 'C:\portable'
)
# Do some magic here to set the CSV / hash headers so I can use them as shown below
Foreach ($app in $mycsv) {
Write-Host "App Name: $app.name"
Write-Host "App Type: $app.type"
Write-Host "App id : $app.id"
Write-Host "App Loc : $app.type"
Write-Host ("-"*40)
}
</code></pre>
<p>I'm sure you see where I am going.</p>
<p><strong>So how can I process the inline CSV line-by-line using the header names?</strong></p>
<p>Expected output:</p>
<pre><code>App Name: Brave
App Type: 1
App id : Brave.Brave
App Loc : winget
----------------------------------------
...
</code></pre>
<hr />
<p><strong>UPDATE: <code>2022-12-03</code></strong></p>
<p>The ultimate solution is the following very brief and non-verbose code:</p>
<pre><code>$my = @'
name,id,type,loc
Brave, Brave.Brave,1,winget
"Adobe Acrobat (64-bit)",{AC76BA86-1033-1033-7760-BC15014EA700},2,
GitHub CLI,GitHub.cli,,C:\portable
'@
ConvertFrom-Csv $my | % {
Write-Host "App Name: $($_.name)"
Write-Host "App Type: $($_.type)"
Write-Host "App id : $($_.id)"
Write-Host "App Loc : $($_.loc)"
Write-Host $("-"*40)
}
</code></pre>

<p>I’m a beginner in the field of Graph Matching and Parallel Computing. I read <a href="https://arxiv.org/abs/1302.4587" rel="nofollow noreferrer">a paper</a> that talks about an efficient parallel matching algorithm. They explained the importance of the locality, but I don't know it represents what? and What is good and bad locality?</p>
<blockquote>
<p>Our distributed memory parallelization (using MPI) on p processing elements (PEs or MPI processes) assigns nodes to PEs and stores all edges incident to a node locally. This can be done in a load balanced way if no node has degree exceeding m/p. The second pass of the basic algorithm from Section 2 has to exchange information on candidate edges that cross a PE boundary. In the worst case, this can involve all edges handled by a PE, i.e., we can expect better performance if we manage to keep most edges locally. In our experiments, one PE owns nodes whose numbers are a consecutive range of the input numbers. <strong>Thus, depending on how much locality the input numbering contains we have a highly local or a highly non-local situation.</strong></p>

<p>LinkedHashMap has underlying double-linked list, which enables preservation of the insertion order during the iteration. Non-structural changes, i.e. replacement of the value of an already inserted key, does not affect iteration order. However, I am still wondering, <strong>whether remove(key) operation changes the iteration order in LinkedHashMap</strong>. As I have tested on really small examples, it does not affect the order of the elements, except for the missing element, which is not included during iteration, obviously - but anecdotes are not proofs. Supposedly, removal works as if in LinkedList (where the halves of the list split are at the index of the element are joined together) - on the other hand, the programmer maybe should take into account rehashing or reallocation.</p>
<p>I am really confused and after reading the documentation of LinkedHashMap thoroughly, also still very doubtful, as I need a structure which preserves the order of insertion but enables an easy lookup and removal of the entries.</p>

<p>I have difficulties creating a counter (which is errorCount) for my while loop statement. I want my counter to function so that if the user answered a question incorrectly 5 times the program will terminate. furthermore, I have 3 questions for the user and I want to accumulate all the errorCounts so that if it hit 5 the program will terminate.</p>
<p>for example: if the user answers question 1 incorrectly twice then the errorCount will be two. If the user answers question 2 incorrectly three times then the program will be terminated. However, the program is allowing the user to make 5 mistakes for every problem.</p>
<pre><code># Level 5:
print("You have the jewel in your possession, and defeated Joker at his own game")
print("You now hold the precious jewel in your hands, but it's not over, you must leave the maze!")
print("*You must now choose 'Right', 'Left', or 'Straight' as you exit the maze. Keep trying until you find your path.*")
# put an error limit
# space everything out to make it look more neat
# Make sure you can fail the level
**errorCount = 0**
position = 0
while True:
answer1 = input("Choose either Right, Left, Straight: ")
try:
if answer1.lower() == "right":
print("You have chosen the correct path, now you proceed to the next step!")
print()
break
*
if errorCount == 5:
print("you made too many mistakes and got captured, you have to restart")*
elif answer1.lower() == "left":
print("You see a boulder blocking your path which forces you to go back.")
errorCount = 1 + errorCount
elif answer1.lower() == "straight":
print("On your way to the next stage you are exposed to a toxic gas that forces you to go back .")
errorCount = 1 + errorCount
else:
print("Wrong input. Please try again..")
errorCount = 1 + errorCount

<p>Consider the following snippet:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>#parent {
display: grid;
grid-template-columns: repeat(2, 1fr);
grid-template-rows: repeat(2, 1fr);
width: 275px;
border: 2px solid green;
padding: 10px;
}
input {
background-color: hotpink;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><div id="parent">
<input />
<input />
<input />
<input />
</div></code></pre>
</div>
</div>
</p>
<p>If you run the snippet, you will find that the inputs overflow the parent div along the x-axis and refuses to fit inside the div (tested in Chromium-based Edge). Basically, when you give the parent with <code>display: grid</code> a fixed width, the input children don't seem to fit.</p>
<p>I've tried all the properties I could think of, but none of them seemed to keep the inputs where they belong (I expect a nice 2x2 grid where the children fit evenly into the grid). How can I keep the inputs in the grid?</p>

<p>I would like my array to from index to index like thisfor example: (0,0), (1,0), (2,0) etc. I've tried what seems like it should be the right way, but my loops stop after the first column and I get an index out of bounds exception.</p>
<p>Here's what I did:</p>
<pre><code>int[][] array2d =
{
{4,5, 3,8},
{8,3,99,6},
{5,7, 9,1}
};
</code></pre>
<pre><code>int currentRow = 0;
for (int currentColumn = 0; currentColumn < (array2d[currentRow].length); currentColumn++)
{
for(currentRow = 0; currentRow < array2d.length; currentRow++)
{
System.out.println(array2d[currentRow][currentColumn]);
}
}
</code></pre>

<p>Say I have a table:</p>
<pre class="lang-sql prettyprint-override"><code>CREATE TABLE staff (
id INT,
name CHAR(9)
);
</code></pre>
<p>With data:</p>
<pre><code>INSERT INTO staff (id, name) VALUES (1, 'Joe');
INSERT INTO staff (id, name) VALUES (2, 'Bob');
INSERT INTO staff (id, name) VALUES (3, 'Alice');
</code></pre>
<p>I need to create a multi row UDF, something like the built-in <code>AVG</code> function, such that I can call it in the following manner:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT vowel_count(name) FROM staff;
</code></pre>
<p>And assuming vowels are <code>[AaEeIiOoUu]</code>, get the following result:</p>
<pre><code>| vowel_count(name) |
|-------------------|
| 6 |
</code></pre>
<p>What is the syntax to take a table column as input to a UDF?</p>
<pre class="lang-sql prettyprint-override"><code>CREATE OR REPLACE FUNCTION vowel_cnt(/* what goes here? */)
RETURN NUMBER
IS
...
BEGIN
...
END;
</code></pre>
<p>The function must be table agnostic, just like <code>SUM</code>, <code>AVG</code>, etc.</p>
<p>I am using Oracle PL/SQL and SQL Developer.</p>

<text dominant-baseline="rrr" class="rv-xy-plot__series--label-text">0.00%</text>
</g>
</svg>
</code></pre>
<p>I am trying to get the Categories and corresponding Percentages from the last 2 blocks of the SVG, I've replaced all the values with the string 'rrr' just to make it more readable here.</p>
<p>I'm trying,</p>
<pre><code>driver.find_element(By.XPATH,"//*[local-name()='svg' and @class='rv-xy-plot__inner']//*[local-name()='g' and @class='rv-xy-plot__series rv-xy-plot__series--label typography-body-medium-xs text-primary']//*[name()='text']").get_attribute('innerText')
</code></pre>
<p>Like I said, I don't know what I'm doing here, what I've so far understood is svg elements need to be represented as a 'custom ?' XPATH which involves stacking all elements into an XPATH which is relative to each other, however I have no clue on how to extract the expected output like below.</p>
<pre><code>Category 1 - 44.83%
Category 2 - 0.00%
</code></pre>
<p>Any help is appreciated. Thanks.</p>

<p>I have many string to match against a regex. Many strings start with the same substring. To speed up my search, I would like to check whether the regex could match a string which begins with the common substring...</p>
<h5>Example</h5>
<p>I have a regex like for instance: <code>/^(.[3e]|[o0]+)+l+$/</code> and many strings, like for instance these:</p>
<pre><code>...
goo
goober
good
goodhearted
goodly
goods
goody
goof
goofball
google
goon
goose
...
held
helical
helices
helicopter
helipad
heliport
hell
help
hellion
helm
helmet
...
</code></pre>
<p>Half of the strings start with <code>goo</code>: I'd like to test whether <code>goo</code> is a valid beginning for a match. It's not (no string starting with <code>goo</code> can ever match that regex), thus I'd discard all those words at once.</p>
<p>The other half start with <code>hel</code>: I'd like to test whether <code>hel</code> is a valid beginning for a match. It is (some strings starting with <code>hel</code> may match that regex), thus I proceed testing those strings.</p>
<p>Is there any function to do this with a generic regex, without having to manually re-engineer it?</p>

<p>I've been trying to get this to work forever and still no luck</p>
<p>I have:</p>
<ul>
<li>GTX 1050 Ti (on Lenovo Legion laptop)</li>
<li>the laptop also has an Intel UHD Graphics 630 (i'm not sure if maybe this is interfering?)</li>
<li>Anaconda</li>
<li>Visual Studio</li>
<li>Python 3.9.13</li>
<li>CUDA 11.2</li>
<li>cuDNN 8.1</li>
<li>I added these to the PATH:
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2\libnvvp</li>
<li>finally I installed tensorflow and created its own environment</li>
</ul>
<p>and I still can't get it to read my GPU</p>
<p>basically followed <a href="https://www.youtube.com/watch?v=hHWkvEcDBO0&t=295s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=hHWkvEcDBO0&t=295s</a></p>
<p>AND I'm still having no luck.</p>
<pre><code>from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
</code></pre>
<p>yields only information on the CPU</p>
<p>Can anyone please help?</p>

<p><a href="https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#option_mysqldump_single-transaction" rel="nofollow noreferrer">MySQL documentation</a> says</p>
<blockquote>
<p>--single-transaction</p>
</blockquote>
<blockquote>
<p>This option sets the transaction isolation mode to <strong>REPEATABLE READ</strong> and sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with transactional tables such as InnoDB, because then it dumps the consistent state of the database at the time when START TRANSACTION was issued without blocking any applications.</p>
</blockquote>
<p>My doubt is that, it says the isolation is set as <strong>REPEATABLE READ</strong>, but this may not guarantee a consistent database state.</p>
<p>For example, if we have a table <code>Employee</code>, and a table <code>Hobby</code>, and a table <code>EmployeeHobby</code> which stores employee id and hobby id.</p>
<p>When we use <code>–single-transaction</code> (i.e., <code>REPEATABLE READ</code>) to dump the database. Let's denote the transaction as <code>A</code>.</p>
<p>In <code>A</code> we first dump table <code>Employee</code>, then some concurrent transaction <code>B</code> insert a new employee into <code>Employee</code>, and <code>B</code> adds related hobby into <code>Hobby</code> and <code>EmployeeHobby</code> (this does not violate <code>REPEATABLE_READ</code> since <code>A</code> never reads <code>Employee</code> afterwards), and then <code>A</code> dump table <code>EmployeeHobby</code> and <code>Hobby</code>.</p>
<p>Eventually, the dumped data by <code>A</code> is not consistent, since <code>EmployeeHobby</code> contains the id of a employee that does not exist in <code>Employee</code>.</p>
<p>The dumped data is broken, isn't it?</p>
<p>What the doc says</p>
<blockquote>
<p>it dumps the consistent state of the database at the time when START TRANSACTION was issued</p>
</blockquote>
<p>seems not to be achievable by setting it to be a <code>REPEATABLE READ</code> transaction.</p>

<p>Let's say I have a c# project Foo and a classlibrary called Bar</p>
<p>I'm wanting to develop Bar alongside Foo which will use Bar as a shared library. I'd like to keep these Foo and Bar in their own git repositories.</p>
<p>When I debug Foo, I'd like to be able to step into Bar to see what it's doing under the hood. When I make changes to Bar, I'd like to be able to have my changes reflected in Foo. It's okay if I'd have to build Bar first for my changes to take effect.</p>
<p>When I eventually deploy Foo, I'd like to import Bar as a nuget package, rather than including it as a part of the solution for Foo</p>
<p>Is this possible in c#? I've been trying to develop a shared library and a repository that uses that library as a template for future projects. I've tried to publish Bar as a nuget package to my local filesystem but it's been giving me problems; I'm unable to step into functions that call into Bar from project Foo and when I make changes to Bar I have to build, pack, then publish the library again. If I don't bump the version number of bar when I do this, this results in errors where I have to go to the nuget package in my filesystem and delete it manually.</p>
<h2>Aside</h2>
<p>If you're interested Bar contains extension methods for setting up a connection to a message broker along with classes for configuration definition and "contract" classes that need to be shared among projects.</p>

<p>I am having trouble getting multiple number vars from a read in line. For a single value I can do strtol(), but how can I get the float and long values of a sentence that is similar to as follows.</p>
<blockquote>
<p>Please aim 3.567 degrees at a height of 5 meters.</p>
</blockquote>
<p>I tried doing two different calls to my buffer sentence, however it got neither of my values. I have no issues with get single values, but with to, I get 0.000 from my strtof call and 0 from mmy strtol call.</p>

<p>I want to add the above array into a data object in javascript as follows.</p>
<pre><code>{
"data": [
//my data here.
]
}
</code></pre>
<p>I have tried this;</p>
<pre><code> let mydata = {

}
</code></pre>
<p>but is places back slashed a lot like this snippet;</p>
<pre><code>{
"data": "[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Point\",\"coordinates\"...
</code></pre>
<p>How do I remove the back slashes in javascript please?</p>
<p>This is the specific code;</p>
<pre><code> let skidata = JSON.stringify(uniqueFeatures);
let mydata = {
"data": skidata
}
console.log((mydata));
</code></pre>
<p>When I console.log skidata, there are no backslashes. When I console.log mydata, back slashes are added, I think. This is a pict of console.log(mydata)</p>

<p>Both <code>.</code> and <code>::</code> can be used to call class methods, but, in my experience, <code>.</code> is by far the most commonly used of the two. So I am accustomed to using that form in documentation and RSpec describe/context/expect strings.</p>
<p>However, the Ruby API documentation uses <code>::</code> (e.g. at <a href="https://rubyapi.org/3.1/o/string" rel="nofollow noreferrer">https://rubyapi.org/3.1/o/string</a>). Is that intended to mean that that form is preferred for the cases I described?</p>
<p><a href="https://i.stack.imgur.com/nUBac.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nUBac.png" alt="enter image description here" /></a></p>
<p>Note: This is <em>not</em> a duplicate of <a href="https://stackoverflow.com/questions/43134/is-there-a-difference-between-and-when-calling-class-methods-in-ruby">Is there a difference between :: and . when calling class methods in Ruby?</a>. That question refers to the use of the two alternate notations in Ruby source code, whereas this question refers to documentation and other textual descriptions (e.g. in rspec strings). There may be reasons to make different choices in code vs. documentation, for example, that using <code>.</code> in code more clearly indicates a message call vs. a constant access, whereas in documentation <code>::</code> might be preferred to more dramatically distinguish class methods from instance methods.</p>

<p>I am trying to figure out recursion and how it operates and I cant seem to figure out what is happening in this code.</p>
<pre><code>def printFun(test):
if (test < 1):
return
else:
print(test, end="a ")
printFun(test-1) # statement 2
print(test, end="n ")
return
# Driver Code
test = 3
printFun(test)
</code></pre>
<p>This outputs</p>
<pre><code>3a 2a 1a 1n 2n 3n
</code></pre>
<p>I can make sense of the first 4 outputs.
test = 3, which not less than 1, so print test(1a), then re-call the printFun function with test-1
being 2, which is not less than 1, so print test (2a), then (1a) then 0, which IS less than 1
so return. I assume this brings you back to the</p>
<pre><code>print(test, end='n')
</code></pre>
<p>line? which now prints 1n.</p>
<p>This is where I am left perplexed... what is happening beyond this??? How does it start ascending and then stop again at 3? What is the flow and logic of this?
Sorry if this is a ridiculous question and I am overlooking something blatantly obvious.</p>
<p>But I cannot wrap my mind around this...
Anyone?</p>
<p>Thanks!</p>

<p>How do I loop through this dictionary correctly?</p>
<p>I want it to say</p>
<p>I dont agree with your favorite food Bill.
Cake is delicious but not that good!</p>
<p>I dont agree with your favorite food Alex.
Patacones are delicious, but not that good!</p>
<p>I appreciate all the help. Thank you.</p>
<p>The code cycles through all of the values instead of stopping after one. I googled the endswith function to see if I could get the code to print something different if the value ended in 's' but it didnt work. Before I added that line it printed the following.</p>
<p>I dont agree with your favorite food Bill.
Cake is delicious, but not that good!
Cake are delicous, but not that good!
Patacones is delicious, but not that good!
Patacones are delicous, but not that good!
I dont agree with your favorite food Alex.
Cake is delicious, but not that good!
Cake are delicous, but not that good!
Patacones is delicious, but not that good!
Patacones are delicous, but not that good!</p>
<p>I wanted to find a way to trigger "are" when the value was plural and "is" if the value was singular.</p>

<p>I'm trying to make a game which is spawning an object and after the object is destroyed, another object spawns right away. But right now I'm trying to destroy an instantiate object in a different function, and it is not working.</p>
<p>`</p>
<pre><code> public GameObject[] food;
public Vector3Int spawnPosition;
public void Start()
{
SpawnFood();
}
//Spawning food
public void SpawnFood()
{
int random = Random.Range(0, food.Length);
GameObject clone = (GameObject)Instantiate(food[random], this.spawnPosition, Quaternion.identity);
}
private void Update()
{
if(Input.GetKeyDown(KeyCode.C))
{
Destroy(this.gameObject);
}
}
</code></pre>
<p>`</p>
<p>I have tried to do some research on this and still, I can only find the solution for destroying an object inside the same function as the Instantiate.</p>

<p>I am doing an assignment in which I need to open a raw mailing list, saved in a CSV file, filter the users that have been unsubscribed, and print back the resulting mailing list to another CSV file.

<p>I'm trying to use a loop or an apply family solution for the next problem. I have few dataframes such as:</p>
<pre><code>df1 <- data.frame(a = c(1,2,3,NA,NA,NA,NA,NA,9,NA),b = c(1,2,3,4,NA,NA,NA,8,9,10),c = c(1,2,3,NA,NA,NA,7,8,NA,NA))
df2 <- data.frame(a = c(1,2,3,4,5,6,NA,NA,NA,10),b = c(1,2,3,4,NA,NA,NA,8,9,10),c = c(1,2,3,NA,NA,NA,7,8,NA,NA))
df5 <- data.frame(a = c(1,2,3,4,5,6,NA,NA,9,10),b = c(1,2,3,4,5,6,NA,8,9,10),c = c(1,2,3,NA,NA,NA,7,8,9,NA))
</code></pre>
<p>where Im trying to use na.approx to fill in some NA gaps. What I had in mind is:</p>
<pre><code>l <- c(1,2,5)
for (i in l){
df[[i]] <- df[[i]] %>% mutate(a = na.approx(a, na.rm = FALSE))
df[[i]] <- df[[i]] %>% mutate(b = na.approx(b, na.rm = FALSE))
df[[i]] <- df[[i]] %>% mutate(c = na.approx(c, na.rm = FALSE))
}
</code></pre>
<p>with this example Im getting the following error:</p>
<pre><code>Error in UseMethod("mutate") :
no applicable method for 'mutate' applied to an object of class "c('double', 'numeric')"
</code></pre>
<p>and with my actual data Im getting this error:</p>
<pre><code>Error in `vectbl_as_col_location2()`:
! Can't extract columns past the end.
i Location 13101 doesn't exist.
i There are only 16 columns.
</code></pre>
<p>where "13101" would be part of a dataframe named "df13101".</p>
<p>When I check class of dataframes, I get</p>
<pre><code>[1] "data.frame"
</code></pre>
<p>for the example but my actual dataframe I get</p>
<pre><code>[1] "grouped_df" "tbl_df" "tbl" "data.frame"
</code></pre>
<p>and when I check the type of each variable I want to mutate all are numeric (example and real ones).</p>
<p>I need to understand how to properly call these dataframes and what problems I could face because of the data class or the usage of mutate. I've tried using mapply but I'm very new to R and I'm barely learning about the whole apply family.</p>
<p>Any help would be great, thanks for reading!</p>

<p>here I'm using another lib for my tests, I don't think the problem is here, because I already used this way to do my tests several times, and it worked perfectly, but for some reason, now this is happening to me, I don't know if everything is a typo error of my self or not, but I already checked it a lot of times</p>

<p>I am doing my first Python program and its Hangman game. I managed to make it work but as a part of the task I need to write "best results -hall of fame" table as json file. Each entry in the table should consist of name of the person and the result they achieved (number of tries before guessing a word). My idea is to use dictionary for that purpose and to append the result of each game to that same dictionary.</p>
<p>My code goes like this:</p>
<pre><code>with open("hall.json","a") as django:
json.dump(hall_of_fame, django)
</code></pre>
<p>hall_of_fame is a dictionary where after playing a game the result is saved in the form of <code>{john:5}</code></p>
<p>The problem I have is that after playing several games my .json file looks like this:</p>
<pre><code>{john:5}{ana:7}{mary:3}{jim:1}{willie:6}
</code></pre>
<p>instead I want to get .json file to look like this:</p>
<pre><code>{john:5,ana:7,mary:3,jim:1,willie:6}
</code></pre>
<p>What am I doing wrong? Can someone please take a look?</p>

<p>I am trying to set up audit properties for each of my Entities with an abstract Base class</p>
<pre><code>public abstract class Base
{
public bool IsActive { get; set; }
public bool IsDeleted { get; set; }
public int CreatedByUserId { get; set; }
[ForeignKey("CreatedByUserId")]
public virtual User CreatedBy { get; set; }
public int ModifiedByUserId { get; set; }
[ForeignKey("ModifiedByUserId")]
public virtual User ModifiedBy { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateModified { get; set; }
}
</code></pre>
<p>Somehow the Data Annotations doesn't work in EF Core but was working in my EF 6 Project
I am now receiving this error:</p>
<pre><code>Unable to determine the relationship represented by navigation 'Address.CreatedBy' of type 'User'. Either manually configure the relationship, or ignore this property using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'.
</code></pre>
<p>These are my models:</p>
<pre><code>public class Address : Base
{
public int Id { get; set; }
public string StringAddress { get; set; }
public string City { get; set; }
public string State { get; set; }
public string ZipCode { get; set; }
public int UserId { get; set; }
public User User { get; set; }
}
public class User : Base
{
public int Id { get; set; }
public string FirstName { get; set; }
public string MiddleName { get; set; }
public string LastName { get; set; }
public DateTime BirthDate { get; set; }
public string Email { get; set; }
public string ContactNumber { get; set; }
public string SecondaryContactNumber { get; set; }
public int RoleId { get; set; }
public Role Role { get; set; }
public HashSet<Address> Addresses { get; set; }
}
</code></pre>
<p>What's weird is when I remove the Base inheritance from my other entities apart from User, EF Core is able to set the FK without any errors.</p>
<p>How do I configure it manually with Fluent API?
I already have a BaseConfig class as starting point to be inherited by my other entity config classes:</p>
<pre><code>public class BaseConfig<TEntity> : IEntityTypeConfiguration<TEntity> where TEntity : Base
{
public virtual void Configure(EntityTypeBuilder<TEntity> builder)
{
builder.Property(x => x.DateCreated).HasDefaultValueSql("GETDATE()");
builder.Property(x => x.DateModified).HasDefaultValueSql("GETDATE()");
// Am I setting this correctly?
builder
.HasOne(b => b.CreatedBy)
.WithMany()
.HasForeignKey(p => p.CreatedByUserId);
}
}
</code></pre>

<p>I'm working with the following table where you can get activity from customer purchases.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>DateOfActivity</th>
<th>CustomerReference</th>
<th>Reference Line</th>
<th>Description</th>
<th>Receivable Amount</th>
</tr>
</thead>
<tbody>
<tr>
<td>24/10/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Credit Purchase</td>
<td>20,000</td>
</tr>
<tr>
<td>24/10/2022</td>
<td>CUST567</td>
<td>4</td>
<td>Credit Purchase</td>
<td>10,000</td>
</tr>
<tr>
<td>24/10/2022</td>
<td>CUST555</td>
<td>2</td>
<td>Credit Purchase</td>
<td>50,000</td>
</tr>
<tr>
<td>27/10/2022</td>
<td>CUST555</td>
<td>2</td>
<td>Contract Sign</td>
<td>0</td>
</tr>
<tr>
<td>27/10/2022</td>
<td>CUST567</td>
<td>4</td>
<td>Contract Sign</td>
<td>0</td>
</tr>
<tr>

<td>1</td>
<td>Contract Sign</td>
<td>0</td>
</tr>
<tr>
<td>27/10/2022</td>
<td>CUST567</td>
<td>4</td>
<td>Repayment</td>
<td>-3,500</td>
</tr>
<tr>
<td>27/10/2022</td>
<td>CUST567</td>
<td>4</td>

<td>-3,000</td>
</tr>
</tbody>
</table>
</div>
<p>I'm using the following query to extract the above table:</p>
<pre><code>Select
DateOfActivity, CustomerReferencce, ReferenceLine, Description, ReceivableAmount
From 'Table A'
Where
DateOfActivity >= '2022-09-01'
Group by
DateOfActivity
</code></pre>
<p>As you can see that the table will only get bigger because more customer activity is being added. How can I change my query so the customers who have fully paid their receivable amount don't show up in this table?</p>
<p>The result from above script change that I am expecting is as follows:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>DateOfActivity</th>
<th>CustomerReference</th>
<th>Reference Line</th>
<th>Description</th>
<th>Receivable Amount</th>
</tr>
</thead>
<tbody>
<tr>
<td>24/10/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Credit Purchase</td>
<td>20,000</td>
</tr>
<tr>
<td>24/10/2022</td>
<td>CUST555</td>
<td>2</td>
<td>Credit Purchase</td>
<td>50,000</td>
</tr>
<tr>
<td>27/10/2022</td>
<td>CUST555</td>
<td>2</td>
<td>Contract Sign</td>
<td>0</td>
</tr>
<tr>
<td>27/10/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Contract Sign</td>
<td>0</td>
</tr>
<tr>
<td>13/11/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Repayment</td>
<td>-10,000</td>
</tr>
<tr>
<td>13/11/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Repayment</td>
<td>-2,000</td>
</tr>
<tr>
<td>18/11/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Contract Sign</td>
<td>0</td>
</tr>
<tr>
<td>18/11/2022</td>
<td>CUST567</td>
<td>1</td>
<td>Repayment</td>
<td>-3,000</td>
</tr>
</tbody>
</table>
</div>
<p><strong>CUST567 Reference Line 4</strong> has been removed because the sum of his Credit Purchase + Contract Sign + Repayment = $0. All other Customers rows are still showing up.</p>
<p>How can edit the query so this is done automatically for Large data? Please note the following assumptions:</p>
<ul>
<li><p>Customer Reference for multiple customers can be same or different (for example in above example, CUST567 has two Reference Line 1 & 4. However, CUST555 only has one reference Line 2.</p>
</li>
<li><p>The data is removed for Customers based on Receivable amount coming down to Nil (so all rows for that CustomerReference & Reference Line are removed)</p>
</li>
</ul>
<p>Thanks in Advance</p>

<p>In Rust, we can create a Vector with macro <code>vec![]</code>.</p>
<pre><code>let numbers = vec![1, 2, 3];
</code></pre>
<p>Is there any similar macro that allow us to create a <code>HashSet</code>?</p>
<p>From the doc <a href="https://doc.rust-lang.org/std/collections/struct.HashSet.html" rel="nofollow noreferrer">https://doc.rust-lang.org/std/collections/struct.HashSet.html</a>, I notice that we have <code>HashSet::from</code>:</p>
<pre><code>let viking_names = HashSet::from(["Einar", "Olaf", "Harald"]);
</code></pre>
<p>However, that requires us to create an array first, which seems a bit wasteful.</p>

<p>The parameter in the stored procedure is defined as <code>@latitude decimal</code>. Right before going into the stored procedure, the value is 25.631230</p>
<p>When running the profiler I can see that SQL Server sees the value as: 25.631229999999999</p>
<p>This is obviously a much different value when you are dealing with longitude/latitude.</p>
<pre><code>SqlParameter lat = new SqlParameter { SqlDbType = System.Data.SqlDbType.Decimal, Value = 25.631230, ParameterName = "@latitude" };
cmd.Parameters.Add(lat);
cmd.CommandText = storedProcName;
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.ExecuteReader()
</code></pre>
<p>Hope it's just a setting somewhere ;)</p>

<p>Im using a TMDB API to search for movies and add them to a watchlist.</p>
<p>In this javascript function im getting movie details based on user input and rendering the results to html using bootstrap.</p>
<pre><code>const searchMovie = async (searchInput) => {
try {

let movies = response.data.results;
let displayMovies = '';
$.each(movies, (index, movie) => {

<p>I have another html file called <strong>watchlist.html</strong> that i want to send the movie selected from the search results to that file and build a watchlist.</p>

<p>I am trying to make a call to an API and then grab event_ids from the data. I then want to use those event ids as variables in another request, then parse that data. Then loop back and make another request using the next event id in the event_id variable for all the IDs.</p>
<p>so far i have the following</p>
<pre><code>def nba_odds():
url = "https://xxxxx.com.au/sports/summary/basketball?api_key=xxxxx"
response = requests.get(url)
data = response.json()
event_ids = []
for event in data['Events']:
if event['Country'] == 'USA' and event['League'] == 'NBA':
event_ids.append(event['EventID'])
# print(event_ids)
game_url = f'https://xxxxx.com.au/sports/detail/{event_ids}?api_key=xxxxx'
game_response = requests.get(game_url)
game_data = game_response.json()
print(game_url)
</code></pre>
<p>that gives me the result below in the terminal.</p>
<blockquote>

<p>the URL above format should look like</p>

<p>I'm creating a clone array from an array that contain some empty slots. But after cloning it is being replaced with <code>undefined</code>. If the source array contain some empty slots then clone array should also contain same number and at exact same position empty slots. I don't get the reason. I'm using <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax" rel="nofollow noreferrer"><code>spread syntax</code></a> to clone array as:</p>
<pre><code>const arr = [1, "", , null, undefined, false, , 0];
console.log('arr => ', arr);
const clone = [...arr];
console.log('clone => ', clone)
</code></pre>
<p>Output is as below in chrome console</p>

<p>I'm trying to build a basic terminal that performs basic operations in python. I have made all the main functions, but the cd function isn't working to change my current directory.</p>
<p>I suspect that the problem is in the way I store my current directory file. Perhaps I need to store it as variable instead of using function.</p>
<p>This is the code.</p>
<pre><code>#####################################
# import modules.
# pwd - view the current folder function.
# ls - list files in a folder function.
# touch (filename) - create new empty file function.
# rm (filename) - delete a file function.
# cd - go to another folder function.
# cat (filename) - display the contents of a file function.
######################################
import os
import pathlib
from os.path import join
path = os.getcwd()
# DONE
def ls():
os.listdir(path)
print(os.listdir(path))
def pwd():
print(os.getcwd())
def touch(file_name):
fp = open(join(path, file_name), 'a')
fp.close()
def rm(file_name):
file = pathlib.Path(join(path, file_name))
file.unlink()
def cd(file_name):
os.chdir(join(path, file_name))
while True < 100:
dirName = input()
cmd = dirName.split(" ")[0]
if cmd == "ls":
ls()
elif cmd == "pwd":
pwd()
elif cmd == "cd":
file_name = dirName.split(" ")[1]
cd(file_name)
print(os.getcwd())
elif cmd == "touch":
file_name = dirName.split(" ")[1]
touch(file_name)
elif cmd == "rm":
file_name = dirName.split(" ")[1]
rm(file_name)
elif cmd == 'cd': #
file_name = dirName.split(" ")[1]
cd(file_name)
print(pwd(file_name))
else:
print("Command not found!")
</code></pre>
<p>I tired to change directory using the cd function in my custom terminal, but it's not working. It is expected that cd function to work correctly.</p>

<p>I have a piece of code that contains two functions <code>reverse()</code> that reverses an input list and <code>rotate()</code> that puts the last element to the start of the first.</p>
<p>Now I am given another list, in the function <code>public int minimumOps(List<Integer> a, List<Integer> b)</code> which contains the same elements as the original list but in different order. I am trying to find how many times <code>reverse()</code> and/or <code>rotate()</code> must be called for the new list to be converted back into the original list. For instance, consider <code>S = [1, 2, 3, 4]</code> and <code>T = [2, 1, 4, 3]</code>, we can see that</p>
<pre><code>T = rotate(rotate(reverse(S))) gives us the output
</code></pre>
<p>But this is not the only way to transform S to T. To illustrate, here are some other sequence of operations:</p>
<pre><code>T = reverse(rotate(rotate(S)))
T = rotate(rotate(rotate(reverse(rotate(S)))))
T = reverse(rotate(rotate(reverse(reverse(S))))))
</code></pre>
<p>Our goal in this problem is to find the smallest number of operations to achieve this transformation.</p>
<p>I cannot figure out how to solve this problem. Here is what I have so far:</p>
<pre><code>public int minimumOps(List<Integer> a, List<Integer> b) {
int count = 0;
for (int x = 0; x < a.size(); x++){
if (Objects.equals(a.get(x), b.get(x))){
count += 0;
}
else{
while(!Objects.equals(a.get(x),b.get(x))){
reverse(b);
rotate(b);
count++;
}
}
}
return count;
}
public static List<Integer> rotate(List<Integer> l) {
List<Integer> li = new ArrayList<Integer>();
li.add(l.get(l.size() - 1));
for (int i = 0; i < l.size() - 1; i++) {
li.add(l.get(i));
}
return li;
}
public static List<Integer> reverse(List<Integer> l) {
List<Integer> li = new ArrayList<Integer>();
for (int i = l.size() - 1; i >= 0; i--) {
li.add(l.get(i));
}
return li;
}
</code></pre>
<p>Any ideas on how to approach or solve the <code>minimumOps(a,b)</code> and find the number of <code>rotate()</code> and/or <code>reverse()</code> needed to turn list b into list a would be greatly appreciated</p>
