74,334,712 | <p>I know this is probably a dumb question and I am missing something really simple, but I can't for the life of me figure out where I am going wrong... I am ultimately trying to generate a list of all possible letter combinations with a string of a given length. I know some of these letter combinations wont be pronounceable, but I am going to call them 'words' nonetheless for simplicity. For example, if I know my string is one letter long, I want to generate a list of letters, "A" though "Z", 26 elements long. If I know my string is two letters long, I will need a list of "words" from "AA" to "ZZ", 676 elements long. The rub comes where I do not know the number of letters ahead of time.</p>
<p>If I know my 'word' will only be one letter, then I can do this:</p>
<pre><code>letters = ["A", "B", "C", ... "X", "Y", "Z"]
words = []
for x in range(26):
words.append(letters[x])
print(words)
</code></pre>
<p>If I know my 'word' will be two letters long, I can do this:</p>
<pre><code>letters = ["A", "B", "C", ... "X", "Y", "Z"]
words = []
for x in range(26):
for y in range(26):
words.append(letters[x] + letters[y])
print(words)
</code></pre>
<p>What I can't for the life of me figure out is how to do this when I don't know ahead of time how many letters my word will have. I basically want a formula where I give it the number of letters, and it gives me a list of all the possible words, that number of letters long. Something to the effect of:</p>
<pre><code>def possible_words(word_length):
list_of_words = []
number_of_words = 26 ** word_length
for x in range(number_of_words):
'''generate the new word here'''
list_of_words.append(new_word)
return list_of_words
</code></pre>
<p>Where am I going wrong? What am I missing? I feel like I am so close, I know this has to be a simple problem, but I have been racking my brain for a few hours now and can't figure it out. I feel like the solution lies in something involving recursion? And I think I maybe can't get the numbers to line up with the words because of a combination of zero-indexing and the fact that a 'zero letter' doesn't exist? I don't know, the more I think the more confused I get... Please help! Thanks in advance!</p>
<p>EDIT: Thanks to those who responded and specifically to njp and Thierry Lathuille who directed me towards itertools.product! The solutions was even more pythonic than I could have hoped for! Below is the code I ended up using, in case anyone else comes across the same issue:</p>
<pre><code>import itertools
alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
word_length = 2 # The 2 is just for testing, actual value will be determined programatically...
letter_tuples = itertools.product(alphabet, repeat=word_length)
words = ["".join(letter_tuple) for letter_tuple in letter_tuples]
print(words)
</code></pre>

<p>Why does array2map come back as undefined? That's what it says in the console log and what it says in the error I get as the result of trying to map something undefined. That's my question, I don't know how much more verbose about it I can be, but this site is forcing me to write more.</p>

74,334,802 | <p>I used win32com to read and send an outlook mail, but when i do it creates a pop up which asks me to deny or allow the program to do so, there is a python module which will allow me to press "allow for 10 minutes," and then click allow?</p>
<p>Just wanted to know if there a module which is able to do so similar to what selenium does on web</p>

74,334,807 | <p>I have been trying to create a regex pattern to validate names which would support alphabets, acute accent characters and including these 2 special characters <strong>-</strong> <strong>.</strong></p>
<p>This is the pattern and it works as expected but only after I enter a 3rd character!</p>
<p>So, it doesn't work for 2 characters and returns <strong>false</strong>.</p>
<pre><code>/^[a-zA-ZßẞüÜöÖäÄÑñÁáÀàÂâÉéÈèÊêËëÍíÌìÎîÏïIJijÓóÒòÔôÚúÙùÛûÝýŸÿ\.\-]([a-zA-ZßẞüÜöÖäÄÑñÁáÀàÂâÉéÈèÊêËëÍíÌìÎîÏïIJijÓóÒòÔôÚúÙùÛûÝýŸÿ\s\.\-]+)([a-zA-ZßẞüÜöÖäÄÑñÁáÀàÂâÉéÈèÊêËëÍíÌìÎîÏïIJijÓóÒòÔôÚúÙùÛûÝýŸÿ\s\.\-]$)/.test('RE')
</code></pre>
<p>It works perfectly for >=3 characters and returns <strong>true</strong>.</p>
<pre><code>/^[a-zA-ZßẞüÜöÖäÄÑñÁáÀàÂâÉéÈèÊêËëÍíÌìÎîÏïIJijÓóÒòÔôÚúÙùÛûÝýŸÿ\.\-]([a-zA-ZßẞüÜöÖäÄÑñÁáÀàÂâÉéÈèÊêËëÍíÌìÎîÏïIJijÓóÒòÔôÚúÙùÛûÝýŸÿ\s\.\-]+)([a-zA-ZßẞüÜöÖäÄÑñÁáÀàÂâÉéÈèÊêËëÍíÌìÎîÏïIJijÓóÒòÔôÚúÙùÛûÝýŸÿ\s\.\-]$)/.test('REG')
</code></pre>
<p>What could be going wrong with the pattern which doesn't work for chars less than 3?</p>
<p>Does somebody here recognize this?</p>

74,334,895 | <p>I am looking to replace the NULL values that occur as a result of a SQL JOIN statement, with 'N/A'.
I have tried to set the default value of both related columns from both tables to N/A, however, every time I execute the SQL JOIN statement, I still receive NULL values.</p>
<p>The two tables I have are the clients and Medical_Aid tables, which I have connected using a foreign key called Reg_No. Below is my sql join query</p>
<pre><code>SELECT
clients.Id_Number,
clients.Medical_No,
medical_aid.Name AS Medical_Aid,
clients.First_Name,
clients.Last_Name,
clients.Age,
clients.Gender,
clients.Email,
clients.Telephone
FROM
clients
LEFT OUTER JOIN medical_aid ON clients.Reg_No = medical_aid.Reg_No;
</code></pre>
<p>I have tried to set the default value of the <code>Medical_No</code> and Medical_Name as <code>'N/A'</code> but every time I execute a <code>JOIN</code> statement, NULL values are returned on the <code>Medical_Name</code> column only</p>
<p>Therefore, I am expecting the JOIN Statement to return <code>'N/A'</code> for both the <code>Medical_No</code> and <code>medical_AidName</code></p>

74,334,960 | <p>I have come across different variations when it comes to user authentication and I have seen developers include a userId field AND a username field (both strings) in their database so I wondered if there is an advantage if you have both of these fields.</p>
<p>I would rather have only one field (username) to have a better overview and prevent possible mistakes but I'm not sure if there could be problems that come along with that variation.</p>
<p>I've already looked on the internet but only found a Quora answer which stated it would make sense to have a userId as an integer since "Integers are easier/faster/less expensive to sort, search, and compare than strings"</p>

74,334,979 | <p>Im trying to make a thing that can detect whether or not a user wants their password stored for next time they run the program, The reason im using a boolean for this is so in the files that need to use the password they can check to see if storepass is True then get the pass/user from a .env if not they can get the password from the storepasswordquestion file amd use that and it wont get stored when the user closes the program.</p>
<p>I have a file called booleans that im using to store booleans, in it is this:</p>
<pre><code>storepass = False
</code></pre>
<p>In a other file called storepasswordquestion i have:</p>
<pre><code>import booleans
username = 'username'
password = 'password'
question = input('Would you like your password to be stored for use next time?') # enter y
if question == 'y':
booleans.storepass = True
# store password/username in .env
</code></pre>
<p>As i understand it import booleans loads the booleans file, Then i think booleans.storepass is like a variable but like a copy of the one in booleans? Because when i go on the booleans file again its still False.</p>
<p>Im needing to change storepass to True in the booleans file and then save it.</p>

void create(int *T,int n){ int i; printf("tab: ");
for(i=0;i<n;i++) scanf("%d",&T[i]);

74,335,047 | <p>I am working with a very large dataset, and am looping over chunks of data to add elements to a class. There are many duplicated values in my data, meaning that I am creating a class instance for the same data many times. From some of the testing I've done, it seems that actually creating the instance of the class is the most expensive part of the operation so I want to minimise this as much as possible.</p>
<p>My question is:
<strong>What is the least expensive (time) way of avoiding creating duplicate class instances? Ideally I would like to create a class instance once only and all duplicates reference the same instance</strong>. I can't remove duplicates from my data at the outset, but I want to make sure I minimise any costly procedures.</p>
<p>Here is a toy example that I hope illustrates my problem. The commented out section shows my thinking for how I might be able to shave off time.</p>
<p>In this example <code>Person</code> contains 2 methods that call <code>sleep</code> to demonstrate a time cost to creating an instance. In my example, the code will run in 4.22 seconds (<code>(SLEEP_1 * 6) + (SLEEP_2 * 6)</code>). Seeing as I have a person "James" present 3 times, I am looking to find a way to add this person only once, and then reference this for the 2 duplicates.</p>
<p>I would then expect the code to run in ~2.8s (<code>(SLEEP_1 * 4) + (SLEEP_2 * 4)</code>)</p>
<pre><code>import time
from collections import defaultdict
SLEEP_1 = 0.2
SLEEP_2 = 0.5
# A class `Person` has a load of methods,
# meaning that creating an instance has a non-negligible time-cost over millions of calls.
class Person:
def __init__(self, info):
self._id = info['_id']
self.name = info['name']
self.nationality = info['nationality']
self.age = info['age']
self.can_drink_in_USA = self.some_long_fun()
self.can_fly_solo = self.another_costly_fun()
def some_long_fun(self):
time.sleep(SLEEP_1)
if self.age >= 21:
return True
return False
def another_costly_fun(self):
time.sleep(SLEEP_2)
if self.age >= 18:
return True
return False
# Some data to iterate over
# Note that "James" is present 3 times
teams = {

}

team_directory = defaultdict(list)
start_time = time.time()

# p = getattr(Person, '_id') == person['_id']
# team_directory[team].append(p)
# continue
print(f"Person {i + 1} = {person['name']}")
p = Person(info=person)
team_directory[team].append(p)
seen[person['_id']] += 1
finish_time = time.time() - start_time
expected_finish = round((SLEEP_1 * 6) + (SLEEP_2 * 6), 2)
print(f"Built a teams directory in {round(finish_time, 2)}s [expect: {expected_finish}s]")
# Loop over the results to check - I want each team to have 3 people
# (so I can't squash duplicates from the outset
for t in team_directory:
roster = " ".join([p.name for p in team_directory[t]])
print(f"Team {team} contains these people: {roster}")

74,335,052 | <p>I'm relatively new to C/C++, and I'm learning about nested for loops and arrays. The question I'm asking is referring to the code below</p>
<pre><code>int main(){
int N, M;
bool secret = false;
scanf("%d %d", &N, &M); //N is the amount of weapon "The Hero" has, while M is the amount for "The Villain"
int X[N]; // To store the value of "Damage" each weapon has
int Y[M];
for(int i = 0; i < N; i++){
scanf("%d", &X[i]); // Inputting the value to each weapon
}
for(int i = 0; i < M; i++){
scanf("%d", &Y[i]);
}
for(int i = 0; i < N; i++){
for(int j = 0; j < M; j++){
if(X[i] > Y[j]){ //To check if atleast one weapon of "The Hero" can beat all the weapon of "The Villain" (What i was trying to do anyways)
secret = true;
} else{
secret = false;
}
}
}
if(secret == true){
printf("The dark secret was true\n");
} else{
printf("Secret debunked\n");
}
return 0;
}
</code></pre>
<p>I am trying to check if at least one weapon in the X array has a greater value than all of the ones is the Y array(not the sum of Y array). The problem I'm running into is that if I put a the last value in the X array as lower than any of the value in the Y array, it will always return false, and print out out the else statement, because the loop will always got to the last iteration and use that as the statement for the condition.</p>
<p>I was expecting the outcome to be</p>
<pre><code>3 5 // The amount of weapons the Hero and Villain has
4 9 2 // The value of each weapon for the Hero
8 4 6 8 3 // The value of each weapon for the Villain
The dark secret was true // The expected output
</code></pre>
<p>instead, I got</p>
<pre><code>Secret Debunked
</code></pre>
<p>because of the looping to last value in the X array. I tried to stop the if statements using break;, using it in the loop it self, both didn't work as expected. I'm thinking of arranging it first then using specific indexes to compare it. But before trying that I figured to ask here first.</p>

74,335,073 | <p>It comes to a surprise to me when I am trying to implement some compound actions with a BlockingQueue based producer/consumer pattern, which makes me think I most likely have missed something obvious.</p>
<hr />
<h1>1. In short</h1>
<p>I need</p>
<ul>
<li>my consumer to make sequence actions in form of ‘take obj from the queue + do more consumer operations on the obj’ atomic and</li>
<li>My producer to make sequence actions in form of ‘offer obj onto the queue + do more producer operations on the obj’ atomic and</li>
<li>The two above atomic sequences synchronized on the same obj, obviously</li>
</ul>
<p>Without such atomicity, problem may occur, see '<strong>PROBLEM!!</strong>' as an example in the comment in code for the producer in the following section 2.</p>
<p>But I can’t simply put a synchronized block around the call to take() and its associated consumer operations as <strong>when the queue is empty</strong>, this consumer will be stuck there <strong>FOREVER</strong> since it will still possess the sync lock while it waits on the producer to fill the queue with an obj, and that sync lock possession of consumer will in turn stop the producer from entering corresponding critical region to do any 'producing'.</p>
<h1>2. Specially, simplified example code are as the following:</h1>
<h1></h1>
<p>Common code known to the producer and consumer classes:</p>
<pre><code>Queue<QObj> nbq = new ConcurrentLinkedQueue();
BlockingQueue<QObj> bq = new LinkedBlockingQueue<>();
List<String> idList = new LinkedList<>();
Object lockObj = idList;
int Idx = 1;
public static class QObj {
public String id;
public String content;
public QObj(String id, String content) {
this.id = id;
this.content = content;
}
}
</code></pre>
<p>Main logic in producer class:</p>
<pre><code> public void produceBlocking() {
QObj o = new QObj(String.valueOf(Idx), "Content_" + Idx++);
// synchronized(lockObj) {
// no point to include Queue.offer(...) call in a synchronized block as we
// won't be able to use synchronized() in corresponding consumer anyway
// for the reason described above
bq.offer(o);
synchronized (lockObj) {
// PROBLEM!! by now, 'o' could have been 'consumed' already
// hence we shouldn't do the following operations:
// do the associated part of compound action of 'producer'
idList.add(o.id);
// do some more operation as part of this compound action ...
}
// }
}
</code></pre>
<p>Main logic in consumer class:</p>
<pre><code> public void consumeBlocking() {
while (true) {
try {
// synchronized (lockObj) {
// can't simply put synchronized() here to make the following compound action atomic
// - when the queue is empty, this consumer will be stuck here forever since it still possesses
// the lockObj, which stops the producer from entering the critical region to do any 'producing'
QObj o = bq.take();
synchronized (lockObj) {
// do the associated part of compound action of 'consumer'
idList.remove(o.id);
// do some more operation as part of this compound action ...
}
// }
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
</code></pre>
<h1>3. Why has this not been a common problem?</h1>
<h1></h1>
<p>I feel that this must have been a common occurring problem when people are using BlockingQueue, and the fact that I couldn’t really locate anything addressing directly to a similar problem affirms my belief that I might have got something fundamentally wrong.</p>
<p>Can someone give some hint about a direct solution or point out where I thought wrong about this problem?</p>
<h1>4. Alternative Ideas</h1>
<p>I did think of a few ideas as alternatives, but I feel <strong>none of them is addressing this issue directly and all have some drawbacks</strong> (as highlighted '<strong>DRAWBACK!!</strong>' in the comments in the code)</p>
<p>4.1 -
Do a check using Queue.contains() before continue</p>
<pre><code>public void produceBlockingWithCheck() {
QObj o = new QObj(String.valueOf(Idx), "Content_" + Idx++);
bq.offer(o);
synchronized (lockObj) {
// First, Check if the obj could have already been consumed
// DRAWBACK!!: this could be very costly, e.g.
// when 'bq' is a LinkedBlockingQueue, and contains(...) always triggers
// a sequential traversal, the Queue itself can be very large
if (bq.contains(o)) {
// do the associated part of compound action of 'producer'
idList.add(o.id);
// do some more operation as part of this compound action ...
}
}
}
</code></pre>
<p>4.2 -
Adjust the order of ops on the producer, move the Queue.offer() call to the end</p>
<pre><code>public void produceBlockingOrderAdjusted() {
QObj o = new QObj(String.valueOf(Idx), "Content_" + Idx++);
// do the associated part of compound action of 'producer', only before
// calling BlockingQueue.offer(...)
// DRAWBACK!!: even this may work for this simple case, such order adjustment
// won't not be logically possible for all cases, will it?
synchronized (lockObj) {
idList.add(o.id);
// do some more operation as part of this compound action ...
}
bq.offer(o);
}
</code></pre>
<p>4.3 -
Use non-blocking queues instead.</p>
<pre><code>
public void produceNonBlocking() {
QObj o = new QObj(String.valueOf(Idx), "Content_" + Idx++);
synchronized(lockObj) {
nbq.offer(o);
// do the associated part of compound action of 'producer'
idList.add(o.id);
// do some more operation as part of this compound action ...
}
}
public void consumeNonBlocking() {
while (true) {
synchronized (lockObj) {
// kind of doing our own blocking.
QObj o = nbq.poll();
if (o != null) {
// do the associated part of compound action of 'consumer'
idList.add(o.id);
// do some more operation as part of this compound action ...
}
// DRAWBACK!!: if the 'producers' don't produce faster than the 'consumers' consuming,
// this 'miss' could be happening too often and get costly
}
}
}

<p>The Route Component in question is the last one, which render the Template component. The Template Component's code is this:</p>
<pre><code>import template from "../assets/js/templates";
function Template(props) {
const title = function () {
for (let i = 0; i < template.length; i++) {
return `${template[i].title}`
}
}

<iframe src={props.gitPath} title={title.apply()} />
);
}
export default Template;
</code></pre>
<p><strong>What am I trying to do?</strong> I'd like to show the Template Component whit the right gitPath props, according to the path of the Route Component.</p>
<p><strong>What is the problem?</strong> This work but only the first <iframe> is shown, for all the Route that starts with '/portfolio/'. For example: If I type: '/portfolio/firstPortfolio' I can see an iframe element that shows the template I previously built and which is stored on GitHub. However, if I type: '/portfolio/leadershipEvent/' I see again an iframe that shows firstPortfolio project instead of an iframe for the leadershipEvent project.</p>
<p>I have attached some pictures for clarity:</p>
<ol>
<li>If I click on firstPortfolio image
<a href="https://i.stack.imgur.com/oEMXk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oEMXk.png" alt="enter image description here" /></a></li>
</ol>
<p>I actually see the project with the correct URL:
<a href="https://i.stack.imgur.com/nmtuo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nmtuo.png" alt="enter image description here" /></a></p>
<ol start="2">
<li>But, if i click on the leadershipEvent img:
<a href="https://i.stack.imgur.com/ae0kX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ae0kX.png" alt="enter image description here" /></a></li>
</ol>
<p>URL is correct but the src iframe's attribute points again to the firstPortfolio github's url</p>
<p><a href="https://i.stack.imgur.com/2jj97.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2jj97.png" alt="enter image description here" /></a></p>

74,335,130 | <p>Having the following json</p>
<pre><code>[
{
"Value": "100000000",
"Duration": 1
},
{
"Value": "100000001",
"Duration": 2

"Duration": 10
}
]
</code></pre>
<p>and the following definition</p>
<pre><code>interface Duration {
value: string
duration: number
}
</code></pre>
<p>I would like to have a method on Duration interface to be available in all objects</p>
<pre><code>durationInSeconds():number {
return duration*1000
}
</code></pre>
<p>The usage scenario would be:</p>
<pre><code>const all = previousJsonContent
const durations:Duration[] = parseAsObjects(all) // JSON.parse(all)
const firstInSeconds = durations[0].durationInSeconds()
</code></pre>
<h1>Typescript approach</h1>
<p>What is idiomatic to typescript? What is the least intrusive way? Should I use <code>assign</code>, <code>prototype</code>, <code>mixins</code>? The problem is that deserialized json is just a data container while I want to treat it as full Objects with methods assigned according to the types and ideally also deep, at fields that also should have a type.</p>
<h1>Scala approach</h1>
<p>In scala I would create a value class wrapper around the data without performance penalty and use some implicit magic like in <a href="https://www.baeldung.com/scala/rich-wrappers" rel="nofollow noreferrer">https://www.baeldung.com/scala/rich-wrappers</a></p>

<pre><code>\bin>.\myBat.bat "mystring"

<p>What is the safe way to convert the data in the DB without change existing data? or any another idea to solve that issue?</p>
<p><strong>EDIT:</strong> Does converting from FLOAT to VARCHAR and than from VARCHAR to DECIMAL is a safe way?</p>

Can someone please help me out in this?? Thank you</p>

<pre><code>Invoke-WebRequest "https://download.opera.com/download/get/?partner=www&opsys=Windows&arch=x64" -OutFile "$env:Temp\opera_installer.exe"
</code></pre>
<p>How can I manipulate a url like this to:</p>
<ol>
<li>Download the file as if I clicked on the link on the download page?</li>
<li>Get the name of the file that is downloaded (as I see that the full file version is in the file downloaded)?</li>
<li>Redirect that download to a destination of my choosing?</li>

<p>--> but Correct Answer is <code>01000000101000000000000000000000</code></p>
<pre><code>#include <stdio.h>
union intFloat
{
int i;
float f;
};
unsigned show_bits(unsigned input)
{
int checker = input;
int i,counter;
int size = (sizeof(input)*8)-1;
char *buffer = (char*)malloc(size+2);
for(i=size,counter=0; i>=0; i--,counter++)
{
if ( checker == 0)
return 0;
if ( checker == 1 )
return 1;
return (input % 2) + 10 * show_bits(input / 2);
}
}
int main()
{
union intFloat data;
printf("Enter an int for encoding: ");
scanf("%d", &data.i);
printf(" Number = %d ",show_bits(data.i));
printf("\n");
printf("Enter a float for encoding: ");
scanf("%f", &data.f);
//call show bits
printf(" Number = %d ",show_bits(data.f));
return 0;
}
</code></pre>
<p>I've tried to source online answer but every code in C is differently structure. I am a novice in C but would like to get more familiar with the language.</p>

<p>Why?</p>

<p>Thanks</p>
<p>I tried</p>
<pre><code>iframe=driver.find_element(By.XPATH("//iframe[contains(@src,'https://pianomarvel.com/uploads/editSlicings/85810')]"));
</code></pre>
<p>I was expecting it to return an iframe, but instead it returned an error.</p>
<p>I'm trying to identify an iframe. I have two iframes they are both the same class. They have differing src, so I wanted to identify them that way</p>

74,335,356 | <p>I have this values: [0, 0, 0, 0, 1] and I want to write a code that tells me that there is 1 row of 4 zeroes like in the example above, and if there's 2 rows of 4 zeroes like: [0, 0, 0, 0, 1, 0, 0, 0, 0]
henceforth it should say that there are 2 rows of 4 zeroes. How can I do that if you guys could help me??</p>
<p>I haven't tried anything, I only considered counting the zeroes With i index but it just well counts zeroes like there are 4 zeroes, but I want to count how many rows of zeroes are there.</p>

74,335,417 | <p>i have a list named events and loop over it via for loop
through each iteration i update the values of dict and then append it to the list.
so i desire that list items dont be repetitive and be different.

but my question is why it doesn't work when dict definition is out of the for loop?</p>

74,335,542 | <p>This started happening after we upgraded our compileSdkVersion and targetSdkVersion to 31.</p>
<p>To give some background: Our project is currently on react native 0.63.2 and previous compileSdkVersion was 30. We were successfully building android app till a few days back but suddenly it started to fail with the following error:</p>
<pre><code>AAPT: error: resource android:attr/lStar not found
</code></pre>
<p>After some searching online, we followed some solutions here: <a href="https://stackoverflow.com/questions/69021225/resource-linking-fails-on-lstar/69045181#69045181">Resource linking fails on lStar</a>
. We upgraded to compileSdkVersion and targetSdkVersion to 31, did some other related changes
and were able to compile successfully. But the app is now crashing immediately on startup when I run it on Android 13 device. The following are the error logs from logcat:</p>

<p>We have <code>enableHermes</code> set to true.
We also searched solutions for this but everything was applicable for RN 67 and beyond. But we are still on RN 63, so none of those solutions worked. We can try upgrading our RN version but there are some blockers so it is not possible to upgrade right away. For now we would like to solve this specific issue and move on. Any help here would be greatly appreciated.</p>

74,335,547 | <p>I'd like to split an array into <code>n</code> roughly equal sized chunks, without knowing how large these chunks will be beforehand.</p>
<p>Using Numpy, this can be done with <code>array_split</code>:</p>
<pre><code>>>> import numpy
>>> x = [7, 3, 9, 10, 5, 6, 8, 13]
>>> x
[7, 3, 9, 10, 5, 6, 8, 13]
>>> numpy.array_split(x, 3)
[array([7, 3, 9]), array([10, 5, 6]), array([ 8, 13])]
</code></pre>
<p>What's the Java equivalent of doing this? I'm happy to use a library function if available.</p>

<p>I tried adding const thinking it will resolve the issue but I didn't. The code did not run. I Just wanted to add some sort of text box in a page. const Text("Rome"), is the main concern.</p>

74,335,608 | <p>Write an SQL query to report the patient_id, patient_name all conditions of patients who have Type I Diabetes. Type I Diabetes always starts with DIAB1 prefix.</p>
<pre><code>+--------------+---------+
| Column Name | Type |
+--------------+---------+
| patient_id | int |
| patient_name | varchar |
| conditions | varchar |
+--------------+---------+
</code></pre>
<p>This table contains information of the patients in the hospital.</p>
<p><code>patient_id</code> is the primary key for this table. <code>conditions</code> contains 0 or more code separated by spaces.</p>
<p>So this was my solution:</p>
<pre><code>SELECT *
FROM Patients
WHERE conditions LIKE 'DIAB1%' OR conditions LIKE '%DIAB1%' ;
</code></pre>
<p><strong>It worked correctly for all these conditions</strong></p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>patient_id</th>
<th>patient_name</th>
<th>conditions</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Daniel</td>
<td>YFEV COUGH</td>
</tr>
<tr>
<td>2</td>
<td>Alice</td>
<td></td>
</tr>
<tr>
<td>3</td>
<td>Bob</td>
<td>DIAB100 MYOP</td>
</tr>
<tr>
<td>4</td>
<td>George</td>
<td>ACNE DIAB100</td>
</tr>
</tbody>
</table>
</div>
<p><strong>except for this condition</strong></p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>patient_id</th>
<th>patient_name</th>
<th>conditions</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Daniel</td>
<td>SADIAB100</td>
</tr>
</tbody>
</table>
</div>
<p>And in the solution it was shown that there is a space after 1st % which would give you the correct answer:</p>
<p><strong>correct query:</strong></p>
<pre><code>SELECT *
FROM Patients
WHERE conditions LIKE 'DIAB1%' OR conditions LIKE '% DIAB1%' ;
</code></pre>
<p>So, can someone please explain why this query works for that particular condition (SADIAB100) and not the 1st query</p>

74,335,642 | <p>I want to know if there is a way to namespace values, in a similar way that we namespace functions in PHP.</p>
<p>You can have:</p>
<pre><code>namespace pizza\land;
function turn_oven_on(){}
</code></pre>
<p>And you can access that function with <code>pizza\land\hello()</code></p>
<p>I wonder if there is a way to do something similar for values.</p>
<p>This is not correct, I am just illustrating what I mean:</p>
<pre><code>namespace pizza\land;
namespaced $ingredients = array('pepperoni', 'garlic');
</code></pre>
<p>Then access it with <code>$pizza\land\ingredients</code>.</p>
<p>Other parts in the same runtime can do:</p>
<pre><code>namespace pasta\land;
namespaced $ingredients = array('tomato', 'mozzarella');
</code></pre>
<p>Then access it with <code>$pasta\land\ingredients</code>.</p>
<p>Of course that doesn't work, but it serves as an example of what I mean.</p>
<p>I know there is the obvious way, which would be to use the Singleton pattern where the constructor sets the value of a public property for the singleton instance (the one and only one instance of the class).</p>
<p>I dislike this setup, and in that case I prefer to go the killer route and just do <code>global $pseudonamespaced_pizza_land_ingredients</code>.</p>
<p>I wonder, is there anything else I can do to achieve this setup using the latest version of PHP (now 8.1)?</p>
<p><strong>Why?</strong></p>
<p>To have the same effect you have with <code>global</code> but at the same time avoid collision.</p>
<p>Well, let's say I am working with some procedural code and I need a value that can be accessed across multiple functions.</p>
<p>So I want to use that value within the realms of that bunch of functions.</p>
<p>I do not want to wrap all those functions into one Class and then use a property for that class, because in that case I just prefer the Singleton or the global.</p>
<p>Also, if not possible. Why not?</p>
<p>I cannot believe that this hasn't been mentioned before as something to consider for integration into PHP. So, there must be a reason for this not being possible, if it isn't. It would be a cool solution for all those codebases that are mostly procedural and use <code>global</code> way too often... ehem... WordPress...</p>

74,335,759 | <p>I need to find all regular files in a directory, and would like to use the C++20 ranges (not Eric Niebler's range-v3) library. I came up with the following code:</p>
<pre><code>namespace fs = std::filesystem;
std::vector<fs::directory_entry> entries{ fs::directory_iterator("D:\\Path"), fs::directory_iterator() };
std::vector<fs::path> paths;
std::ranges::copy(entries |
std::views::filter([](const fs::directory_entry& entry) { return entry.is_regular_file(); }) |
std::views::transform([](const fs::directory_entry& entry) { return entry.path(); }),
std::back_inserter(paths));
</code></pre>
<p>This works, but I'm uncomfortable with the additional boilerplate of using lambdas; I'm used to the Java 8 streams library, and I don't see why I can't just use member functions directly. This was my first attempt at refactoring:</p>
<pre><code>std::ranges::copy(entries |
std::views::filter(fs::directory_entry::is_regular_file) |
std::views::transform(fs::directory_entry::path),
std::back_inserter(paths));
</code></pre>
<p>This resulted in compiler errors:</p>
<pre><code>error C3867: 'std::filesystem::directory_entry::is_regular_file': non-standard syntax; use '&' to create a pointer to member
error C3889: call to object of class type 'std::ranges::views::_Filter_fn': no matching call operator found
...
</code></pre>
<p>So I tried this:</p>
<pre><code>std::ranges::copy(entries |
std::views::filter(&fs::directory_entry::is_regular_file) |
std::views::transform(&fs::directory_entry::path),
std::back_inserter(paths));
</code></pre>
<p>This fixed the first error, but not the second:</p>
<pre><code>error C3889: call to object of class type 'std::ranges::views::_Filter_fn': no matching call operator found
...
</code></pre>
<p>So I found <a href="https://stackoverflow.com/questions/37697832/using-member-variable-as-predicate">Using member variable as predicate</a>, which looked promising, so I tried:</p>
<pre><code>std::ranges::copy(entries |
std::views::filter(std::mem_fn(&fs::directory_entry::is_regular_file)) |
std::views::transform(std::mem_fn(&fs::directory_entry::path)),
std::back_inserter(paths));
</code></pre>
<p>This resulted in new compiler errors:</p>
<pre><code>error C2672: 'std::mem_fn': no matching overloaded function found
...
</code></pre>
<p>Note, <code>std::bind</code> doesn't appear to work either. Any help would be appreciated, thanks!</p>

74,335,864 | <p>When I have a list of immutable objects, <code>lst</code> and want to get rid of duplicates, I can just use <code>set(lst)</code>:</p>
<pre><code>lst = [0,4,2,6,3,6,4,9,2,2] # integers are immutable in python
print(set(lst)) # {0,2,3,4,6,9}
</code></pre>
<p>However suppose I have a list of mutable objects, <code>lst</code> and want to get rid of duplicates. <code>set(lst)</code> won't work because mutable objects are not hashable - we'd get a <code>TypeError: unhashable type: '<type>'</code>. What should we do in this case?</p>
<p>For example, suppose we have <code>lst</code>, a list of <code>dict</code>s (<code>dict</code>s are mutable and thus not hashable) and some <code>dicts</code> occur multiple times in <code>lst</code>:</p>
<pre><code>d0 = {0:'a', 1:'b', 9:'j'}
d1 = {'jan':1, 'jul':7, 'dec':12}
d2 = {'hello':'hola', 'goodbye':'adios', 'happy':'feliz', 'sad':'triste'}
lst = [d0, d1, d1, d0, d2, d1, d0]
</code></pre>
<p>We want to iterate through <code>lst</code>, but only consider each <code>dict</code> once. If we do <code>set(lst)</code>, we'd get a <code>TypeError: unhashable type: 'dict'</code>. Instead we have to do something like:</p>
<pre><code>def dedup(lst):
seen_ids = set()
for elem in lst:
id_ = id(elem)
if id_ not in seen_ids:
seen_ids.add(id_)
yield elem
</code></pre>
<hr />
<p>Is there a better way to do this???</p>

74,335,925 | <p>I have a table of grant application numbers and their corresponding disciplines given by cell value 1.</p>
<pre><code>import pandas as pd
import numpy as np
data={'Application number':[0,1,2,3,4,5,6,7,8,9],
'Physics':[0,0,1,0,0,0,0,1,1,0],
'Chemistry':[1,0,0,0,0,0,0,0,0,1],
'Biology':[0,1,0,1,0,0,1,0,0,0],
'Mathematics':[0,0,0,0,1,1,0,0,0,0]}
#creation of dataframe
df=pd.DataFrame(data)
#column counting all disciplines per grant
df['All_Discipline_count']=df.loc[:,'Physics' : 'Mathematics'].sum(axis=1)
df.head(10)
</code></pre>
<p>I would like to summarize discipline list and discipline count per grant application. I do that using iloc and multiple nested loops.</p>
<pre><code># Creation of resulting dataframe
dfA = pd.DataFrame(columns = ['Application number', 'Discipline_list', 'All_Discipline_count'])
# Pay attention to how iloc a cell selects. 'Application number' is zeroth column.
i=0 #starts from oth row
j=1 #starts from 1st column
Aanvraag_nummer=0
k=df.columns.get_loc("All_Discipline_count") #column number where the All_Discipline_count is
l=len(df.index)#number of rows
for i in range (0,l):
Discipline_count=0 #introducing zero discipline count
Discipline_list=" " #introducing empty discipline list
for j in range (1,k): #counting columns of disciplines
if (df.iloc[i,j]==1) & (Discipline_count<df.iloc[i,k]): #if the given cell has 1 as value
Discipline_list=Discipline_list+ df.columns[j] #adds a column name to discipline list
Discipline_count+=1 #counts the number of disciplines with 1 as value
if Discipline_count==df.iloc[i,k]:#if all disciplines are counted
Aanvraag_nummer=df.iloc[i,0]
new_row = {'Application number':Aanvraag_nummer, 'Discipline_list':Discipline_list, 'All_Discipline_count':df.iloc[i,k]}
dfA = dfA.append(new_row, ignore_index=True)
dfA.head(10)
</code></pre>
<p>The script works for 10 to 100 applications and 20 disciplines as columns. It also works when there are multiple disciplines are given per grant application.</p>
<p>However, I notice that I get warning while running the code.</p>
<pre><code>/tmp/ipykernel_26718/1290491379.py:19: FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead.
</code></pre>
<p>The code is also slow..Any better method to get the same results?</p>

74,335,986 | <p>So far I've got this program which asks me to write a sentence, then it splits it one word at a time separated by spaces.
The problem is that if I write a 3 word sentence it just prints the first two words. What I'm trying to do is split the sentence with no word limit. I just talked to my teacher and he said I must use the subString method instead of the splitString one. Any ideas?</p>
<p>The code:</p>
<pre><code>package NF2;
import java.util.Scanner;
public class Exercici13 {
public static void main(String[] args) {
//Declaring variables
Scanner ent = new Scanner(System.in);
String sentence;
//LLegim frase
System.out.println("Enter a non-empty text: ");
sentence = ent.nextLine();
if(sentence.length() == 0){
System.out.println("You haven't written anything, exiting the program...");
System.exit(0);
}
//Separate by spaces
String[] splitString = sentence.split(" ");
System.out.println(splitString[0]);
System.out.println(splitString[1]);
}
}
</code></pre>
<p>For example, if I write a 3 word sentence now it only returns me the first two words. Plus I can only use the subString, so I should re-do it all over again and I'm not sure where to start. Keep in mind I'm a total begginner, so it's not okay to use advanced methods.</p>

74,335,990 | <p>So in a lot of my coding problems, I end up doing something along the lines of:</p>
<pre><code>for i in range(10):
for j in range(10):
for k in range(10):
print(i, j, k)
</code></pre>
<p>I was just wondering if there was a simpler way to iterate through multiple ranges of numbers? I want to have it so I can give an argument of <code>4</code> in my function and it iterates through 4 different numbers.</p>
<p>I know that:</p>
<pre><code>for i, j in range(10):
print(i, j)
</code></pre>
<p>will iterate through <code>i</code> and <code>j</code> at the same time.</p>
<p>Any help would be greatly appreciated!</p>

74,336,067 | <p>So im reading the below and i understand why you would do it..
<a href="https://jenkov.com/tutorials/java-exception-handling/exception-wrapping.html" rel="nofollow noreferrer">https://jenkov.com/tutorials/java-exception-handling/exception-wrapping.html</a></p>
<p>example :</p>
<pre><code> try{
dao.readPerson();
} catch (SQLException sqlException) {
throw new MyException("error text", sqlException);
}
</code></pre>
<p>So what if i want to isolate all external exceptions inside the dao layer only, and only use my exceptions. so in the above example i dont want to send SQLEXception inside the constructor, would doing the below be enough. Would it contain enough information :</p>
<pre><code> throw new MyException("error text", sqlException);
</code></pre>
<p>or maybe my constructor should be the following instead</p>
<pre><code>public MyException(String text,Exception ex)
</code></pre>

74,336,075 | <p>First we used Terraform to create our resources along with proper tagging.
But later we identified that the Admin team performed some manual modifications to the resource as part of some issues quick fixes and all. At the end the terraform state file of these resources are out of sync.</p>
<p>Now we have requirement to update the tags of the already provisioned resources (terraform used) with new additional tags to them. When we tried by adding the terraform manifests with the changes for the tagging, and executed terraform plan, and could see that some resources are showing to replace and we are not advised to perform that .</p>
<p>We tried to manually import the changes what performed manually from portal, to the terraform state so that we can apply the tag changes from the terraform itself. But we are facing concerns like cant update the resources in minute level from the portal to the state file?</p>
<p>is there any automated way to tag a list of azure resources as per the tags specified for each resources. and we can update the state file so easily ?</p>

74,336,109 | <p>I am working on combining SVG images into one combined SVG image using ReactJS. Sorry you may think that this is duplicate question. But I have checked all the suggested questions but none of them solved my issue. I have done lot of research in fact spent so many days in figuring out solution for this problem.</p>
<p>I have checked NodeJS sharp library as well to solve this issue. I know you must be wondering why I am checking NodeJS because I am looking for solution related to ReactJS. I was checking that because my frontend is in ReactJS but my backend is in NodeJS so I thought If I couldn't achieve this in ReactJS then I should try to do same in NodeJS. But I found that sharp library can take input as SVG but not providing output in SVG.</p>
<p>Actually I am using NPM package merge-images to create combined image. In this I am passing multiple SVG's and getting output in PNG format as combined image. I am giving my code for reference.</p>
<pre><code>import mergeImages from 'merge-images';
const Avatar = (props) => {
const [src, setSrc] = useState('');
useEffect(() => {
let filteredArray = [
{ "name": "skintone","src": "../images/skintone.svg"},
{ "name": "face","src": "../images/face.svg"},
{ "name": "hair","src": "../images/hair.svg"}
];
mergeImages(filteredArray)
.then(src => {
//this src is the base64 encoded data of image in PNG format
console.log('base64 string', src);
setSrc(src);
})
.catch(err => {
console.log('Error', err)
});
});
return (
{ src ? <div><image src={src} /></div> : <div><p>Image Loading....</p></div> }
)
}
</code></pre>
<p>Above code giving image in PNG format.But I wanted output image in SVG format. So I tried passing MIME format as a parameter like as follows</p>
<pre><code>mergeImages(filteredArray, {format: 'image/svg+xml'})
.then(src => {
//this src is the base64 encoded data of image in PNG format
console.log('base64 string', src);
setSrc(src);
})
.catch(err => {
console.log('Error', err)
});
</code></pre>
<p>But above code also giving output image in PNG format.</p>
<p>Please help me in getting output image in SVG format. If possible suggest me any other library through which I can convert combined image in SVG format.</p>
<p>Thanks in advance.</p>

74,336,110 | <p>I was looking up some unknown book about C++. and faced with this table which title reads.</p>
<p>" ― As the result of inheritance all fields of base class are being inherited by derived class."
<em>And then it shows such table.</em>
<a href="https://i.stack.imgur.com/HamrQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HamrQ.png" alt="inherited fields in derived class" /></a></p>
<p><strong>My question is:
Are private fields and functions from base class accessible (as noted in the confusing table) by derived class during private inheritance?</strong></p>
<p>I have read <a href="https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf#section.11.2" rel="nofollow noreferrer">ISO C++ standard</a>, and there is no any mentions about private fields and private inheritance combined, though I have tried myself to find out, and the code behaves as it supposed to.
Example I used.</p>
<pre><code>
#include <iostream>
using namespace std;
class BASE
{
private:
int x;
};
class DERIVED : private BASE
{
public:
void print_X(void){cout << x << "\n";}
};
int main()
{
return 0;
}
</code></pre>
<p>Then compiler error message says:</p>
<pre><code>main.cpp:23:36: error: ‘int BASE::x’ is private within this context
23 | void print_X(void){cout << x << "\n";}
</code></pre>
<p><em>So now I wonder, whether I do something wrong, or the publisher of that book should correct that pages?!</em></p>

As well, i have this problem: i have created a function called "grettings" in order that when the form in the modal is filled, the user click on the button, then greetings function is launched and insert a greeting message in the modal... i do not find any solution for that.</p>

74,336,186 | <p>I have a spring boot app in which I have added another library (in pom.xml).</p>
<p>This library is also a spring boot library which has created some beans and made the beans available using @Bean. The code snippet in 3rd party library is like this :</p>
<pre><code>@Bean
public CustomObject customObject() {
return new CustomObject();
}
</code></pre>
<p>Now, I am using this library in my application, but I dont see this bean registered with my application.
I checked all the beans registered with application Context and also tried loading from application context. But no luck.</p>
<p>What am I missing here? The purpose of this 3rd party library is to check some config and create this bean, so if I have to manually create this bean, it takes away the whole purpose.</p>

74,336,198 | <p>In PHP, I've created a function to create a JSON file:</p>
<pre><code>function writeJSONData(PDO $conn): void
{
$contentJSON = "SELECT * FROM tb_content";
$contentResultsJSON = $conn->query($contentJSON);
$contentJSONExt = array();
while ($JSON = $contentResultsJSON->fetchAll(PDO::FETCH_ASSOC)) {
$contentJSONExt = $JSON;
}
$infoJSON[] = json_encode(array('movies' => $contentJSONExt));
$target_dir = $_SERVER['DOCUMENT_ROOT'] . "/CineFlex/private/api/api.json";
file_put_contents($target_dir, $infoJSON);
}
</code></pre>
<p>In my HTML file I've created a button which sends the ID of the selected movie:</p>
<pre><code><!-- Edit Button -->
<button onclick="toggleDialog(editMovie, this.id)" id="<?php echo($info['content_id']) ?>Edit Movie</button>
</code></pre>
<p>My JavaScript file contains the function:</p>
<pre><code>// Toggle Dialog
function toggleDialog(dialogName, dialogID) {
// Toggle Dialog Visibility
$(dialogName).fadeToggle(200);
$.getJSON("./private/api/api.json", function (data) {
console.log(data)
})
}
</code></pre>
<p>When I click on the edit button, it prints the entire JSON file in the console. Which is understandable.</p>
<p>Current output:</p>
<pre><code>{
"movies": [
{
"content_id": 15,
"title": "Scream (2022)",
"description": "25 years after a streak of brutal murders shocked the quiet town of Woodsboro, Calif., a new killer dons the Ghostface mask and begins targeting a group of teenagers to resurrect secrets from the town's deadly past."
},
{
"content_id": 16,
"title": "Fear Street: Part Two - 1978",
"description": "Shadyside, 1978. School's out for summer and the activities at Camp Nightwing are about to begin. But when another Shadysider is possessed with the urge to kill, the fun in the sun becomes a gruesome fight for survival."
},
{
"content_id": 17,
"title": "Archive 81",
"description": "An archivist hired to restore a collection of tapes finds himself reconstructing the work of a filmmaker and her investigation into a dangerous cult."
}
]
}
</code></pre>
<p>Now my issue is, I want the "dialogID" to be selected from the JSON file where it matches with "content_id". For example: When I click on a movie with 16 as "dialogID", I want the console to just print everything from that array.</p>
<p>Expected output:</p>
<pre><code>{
"movies": [
{
"content_id": 16,
"title": "Fear Street: Part Two - 1978",
"description": "Shadyside, 1978. School's out for summer and the activities at Camp Nightwing are about to begin. But when another Shadysider is possessed with the urge to kill, the fun in the sun becomes a gruesome fight for survival."

<pre><code>grepl(“[0-9]{2}.[0-9]{2}.[0-9]{2}”, x = df[,1])

74,336,283 | <p>I have a front end (angular) with login form, a back-end for that angular application as my OAuth client (spring dependency) then I have a third application that is the Authorization server and finally the forth is the ressources server.</p>
<p>So I want to know is there is any way to jump the redirect to /login from the authorization server?</p>
<p>I want to login the user with angular login page, then make a get with my OAuth client (spring) for the authorization code flow and then, since i'm not authenticated, instead of getting redirect, I want to get an error "401" and then send a post request with my OAuth client (spring) to the auth server again to login the user that have sent the data previously in angular login page.</p>
<p>Essentially I just wanted to login to my auth server with a custom page that exists in the front end application and let the backend build specially for that front, take over the flow.</p>

<p>My code is the following (I used the same as in the video) :</p>
<pre><code>
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
int fd;
char buf[14];
//write
fd = open("myfile.txt", O_WRONLY | O_CREAT, 0600);
if(fd == -1)
{
printf("Failed to create and open the file. \n");
exit(1);
}
write(fd, "Hello World!\n", 13);
close(fd);
//read
fd = open("myfile.txt", O_RDONLY);
if(fd == -1)
{
printf("Failed to open and read the file. \n");
exit(1);
}
read(fd, buf, 13);
buf[13] = '\0';
close(fd);
printf("buf : %s\n", buf);
return 0;
}
</code></pre>
<p>The terminal shows output "Failed to create and open file". So I think I am using the open() wrong or maybe it has to do with my Ubuntu version?</p>
<p>Can somebody see what I am doing wrong?</p>
<p>I tried changing the order of the flags and tried to change the mode to 0777 and 0700 with no success.</p>
<p>There was a Permission Denied error. For some reason the "myfile.txt" was locked.
<em>chmod u=rwx,g=r,o=r myfile.txt</em> command worked for me. Thanks everyone for the quick help.</p>

74,336,396 | <p>I'm asking a user to input a year from the keyboard. For example users input 2008, How can I get the maximum value of the year from list that user input the value of year?</p>
<p>This is my code:</p>
<pre><code>data_list = [(20070101, 619), (20070102, 615), (20070103, 614), (20080104, 845), (20080105, 840), (20080106, 835), (20090107, 940), (20090108, 970), (20090109, 939), (20090110, 936)]
value_year = 0
input_year = input("Enter year >>>")
for date, value in data_list:
result = str(date)
if result[0:4] == input_year:
if value > value_year:
value_year = value
print ("Maximum of this year:", result, value_year)
</code></pre>
<p>The output should be like this. when user input 2008. how to do that?</p>
<pre><code>Maximum of this year: 20080104 845

74,336,403 | <p>I am stuck in a problem. I want to update my cartesian index.</p>
<p>I have a matrix (<code>x</code>) 200x6 that is binary. 1 if assigned, 0 otherwise. I want to find the cartesian index of when <code>x</code> is 1 in the first 3 columns and in the last 3 elements.</p>
<p>I have the following code:</p>
<pre><code>index_right = findall( x -> x == 1, sol.x_assignment[:,1:3])
index_left = findall( x -> x == 1, sol.x_assignment[:,4:6])
index_left
</code></pre>
<p>However <code>index_right</code> is correct, <code>index_left</code> is wrong as it returns index between 1,2,3 instead of 4,5,6</p>
<pre><code>CartesianIndex(2, 1)
CartesianIndex(3, 1)
CartesianIndex(10, 2)
CartesianIndex(11, 1)
</code></pre>
<p>Expected output:</p>
<pre><code>CartesianIndex(2, 4)
CartesianIndex(3, 4)
CartesianIndex(10, 5)
CartesianIndex(11, 4)
</code></pre>
<p>How can I update <code>index_left</code> to add +3 in the second index for all?</p>

<p>I was thinking of checking the presence of element using iteration first but that beats the purpose of recursion. Is there a way to use recursion to find the element if it's present and if its not</p>

<pre><code>word_list = ["Alzheimer", "Alzheimer's", "Alzheimer.", "Alzheimer?","Cognition.", "Cognition's", "Cognitions", "Cognition"] # and the list goes on

<p>As you can see,there are many identical terms in the list but some of them contain unnecessary puntuations (e.g.: dot, single apostrophe), how can I make all the words normalize (e.g.: "Alzheimers." -> "Alzheimers", "Cognition's" -> "Cognition") ?</p>
<p>Thank you in advance!</p>
<p>I expect a function that to filter out unnecessary single punctuations, I tried the following function but it did not work well:</p>
<pre><code>def word_normalizer(word): # Remove unnecessary single puntuations and turn all words into lower case
puntuations = ["'", '"', ";", ":", ",", ".", "&", "(", ")"]
new_word =""
for punc in puntuations:
if punc in word:
new_word = word.strip(punc)

74,336,557 | <p>I'm struggling to define this problem exactly, which is part of the reason I cannot solve it. Basically, I want to assign numbers to nodes that provides a kind of topological sorting, but if there is a cycle in the graph, which I want to allow, it should assign values to the nodes that essentially count up the distance from nearest non-cycle nodes.<a href="https://i.stack.imgur.com/WCJka.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WCJka.png" alt="enter image description here" /></a></p>
<p>eg, If there were another non-cyclic dependency, the numbers assigned to the nodes may look more like this.</p>
<p><a href="https://i.stack.imgur.com/8yWru.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8yWru.png" alt="enter image description here" /></a></p>
<p>Currently, the numbers assigned are just based on total dependencies, which creates less-than-ideal layouts.</p>

<p>I have a feeling that I might need to use some algorithm involving Strongly Connected Components, but I'm not sure how to apply it to get the desired result. Any help clarifying this issue would be greatly appreciated!</p>
