Simple bulls and cows java game : <p>I try to create a verry simple Bulls and Cows game (<a href="https://en.wikipedia.org/wiki/Bulls_and_Cows" rel="nofollow">https://en.wikipedia.org/wiki/Bulls_and_Cows</a>). The game is for my school project. My knowledge is limited, so I need to make the game using only loops, IF-else constructions and other simple functions.</p>
<p>The written code works somewhat - generate code and understands that number is hited, but did not indicate how many cows and bulls have in the wrong assumptions.</p>
<p>I would be glad if someone point me in the right direction :) Thanks in advance</p>

Angular2 Resolve before CanActivate : <p>I have an Authentication service that implements the Resolve interface to return an observable that is resolved once a user's authentication state is retrieved from the server. </p>
<p>This same authentication service implements the CanActivate interface to block users from accessing a component if they are not logged in.</p>
<p>Currently, the canActivate function is triggered before the resolve function is resolved, meaning it checks the user's login state before the login state has been retrieved from the server.</p>
<p>My question is, how can I prevent the canActivate function being called until resolve is resolved, or otherwise is there another way I can achieve what I want?</p>
<p>Thanks
Max.</p>

I need to store data from html table to mysql database using php : I am new to stackoverflow. I am doing a project with html, css, php and mysql. The project is online vegetable shop which is nearly an ecommerce site. I need to store data from html table(my cart) to mysql database using php. The table looks like this:
http://i.imgur.com/OngFBuP.png
the code for "cart" is:
'<?php
include("session.php");
include_once("config.php");
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<?php

$b = 0;
foreach ($_SESSION["cart_products"] as $cart_itm)

And I am using a php page(buy.php) to store all the data to database. The code for "buy.php" is:
'<?php
include('session.php');
$con=new mysqli("localhost","root","","test");
$total=0;
foreach ($_SESSION["cart_products"] as $cart_itm)
{
$product_name = $cart_itm["product_name"];
$product_qty = $cart_itm["product_qty"];
$product_price = $cart_itm["product_price"];
$product_code = $cart_itm["product_code"];
$subtotal = ($product_price * $product_qty);
$total = ($total + $subtotal);
}
$sql="INSERT INTO cart (Uname,TotalCost,veg_id,quantity)
VALUES('$user','$total','$product_code','$product_qty')";
if($con->query($sql)==true){
echo"data inserted successfully";
}
echo"<br><br><a href='index_2.php'> Return to Your Dashboard</a>
<a href='buy_veg.php'> Buy More Items</a>";
?>'
The problem is this "buy.php" page is actually storing the last record to the database. Image link:

I want to store all the cart items to the database. I need to submit my project tomorrow. Please help me as fast as possible.

How to plot time series data with different categories in ggplot 2 R : This is the data-set
group <- c(1,2,3,1,2,3)
species <- c("rabbit","rabbit","rabbit","plant","plant","plant")
t1 <- c(66,77,80,4,3,1)
t2 <- c(4,5,22,1,2,6)
t100 <- c(56,78,22,1,6,7)
df <- data.frame(group, species,t1,t2,t100)
where ti represents time for the ith time-frame. In my original dataset I have 100 such columns
I need to plot time series for the data such that rows with the same group number have the same colour lines, but different symbols (pch). Ideally I need one symbol for "rabbits" category, and another for "plants.
Here is my attempt
time <- c(1,2,100)
library(ggplot2)
ggplot(df, aes(x = time, y=df[,3:5], colour = group)) #I don't know how to take it from here | 0debug |

What could be the problem ?</p>
<p>It will be very kind if you guide me with it. I am really stuck. </p>

<pre><code>for(auto it=B.begin();it!=B.end();it++) {
cout<<(it->first);
}
</code></pre>
<p>will it give us 4, 2, 6 or keys may come in any order?</p>

How Immutability is Implemented : <p>I am trying to grasp how the <a href="https://hackernoon.com/how-immutable-data-structures-e-g-immutable-js-are-optimized-using-structural-sharing-e4424a866d56" rel="noreferrer">trie</a> and such in immutability is implemented, as relates to immutability in JS. I understand how there is supposed to be significant structural sharing.</p>
<p>My question is say you have a graph sort of structure like this:</p>
<pre><code>a -- b
|
c
|
d -- h
|
e -- i -- l
|
f -- j -- m
|
g -- k -- n
</code></pre>
<p>So then you add an <code>x</code> to the system. I'll try it two different ways:</p>
<pre><code>a -- b
|
c
|
d -- h -- x
|
e -- i -- l
|
f -- j -- m
|
g -- k -- n
</code></pre>
<p>That one is just added as a leaf node.</p>
<pre><code>a -- b
|
c
|
d -- h
|
x
|
e -- i -- l
|
f -- j -- m
|
g -- k -- n
</code></pre>
<p>That one is added in the middle of a path.</p>
<p>I am wondering what the immutable data structure would be to handle these 2 situations. So essentially we have a function <code>f : graph -> graph'</code> that changes the graph into a "new graph", when under the hood it should only be making a small adjustment to the data structure. Not sure how this would look or how it works. My first attempt at an explanation would be something like this...</p>
<p>It starts of in a wrapper object which is like ImmutableJS's API layer on top of the JS objects.</p>
<pre><code> --------------------------
| |
| a -- b |
| | |
| c |
| | |
| d -- h |
| | |
| e -- i -- l |
| | |
| f -- j -- m |
| | |
| g -- k -- n |
| |
--------------------------
</code></pre>
<p>Then you make the change and it creates a <em>new</em> wrapper object.</p>
<pre><code> -------------------------- --------------------------
| | | |
| a -- b | | |
| | | | |
| c | | |
| | | | |
| d -- h --------------------------------- x |
| | | | |
| e -- i -- l | | |
| | | | |
| f -- j -- m | | |
| | | | |
| g -- k -- n | | |
| | | |
-------------------------- --------------------------
</code></pre>
<p>Then likewise for the second example:</p>
<pre><code> -------------------------- --------------------------
| | | |
| a -- b | | |
| | | | |
| c | | |
| | | | |
| d -- h | | |
| | | | |
| o --------------------------------- x |
| | | | |
| e -- i -- l | | |
| | | | |
| f -- j -- m | | |
| | | | |
| g -- k -- n | | |
| | | |
-------------------------- --------------------------
</code></pre>
<p>The boxes are the API objects you use, and the graphs inside are the plain JS data objects.</p>
<p>But in these examples the original graph structure is modified (placing a link to <code>h</code> in the first example, and placing an <code>o</code> placeholder in the second one). So I'm wondering how specifically you would make these things <em>immutable</em>. Every change I make to the graph I would like to "return a new object", but under the hood there is optimal structural sharing.</p>
<p>Thank you for your help.</p>

Make Selenium wait 10 seconds : <p>Yes I know the question has been asked quite often but I still don't get it. I want to make Selenium wait, no matter what. I tried these methods </p>
<pre><code>driver.set_page_load_timeout(30)
driver.implicitly_wait(90)
WebDriverWait(driver, 10)
driver.set_script_timeout(30)
</code></pre>
<p>and other things but it does not work. I need selenium to wait 10 seconds. <strong>NO</strong> not until some element is loaded or whatever, just wait 10 seconds. I know there is this </p>
<pre><code>try:
element_present = EC.presence_of_element_located((By.ID, 'whatever'))
WebDriverWait(driver, timeout).until(element_present)
except TimeoutException:
print "Timed out waiting for page to load"
</code></pre>
<p><strong>I do not want that</strong>.</p>
<p>If waiting for some seconds is to much (not achievable) for selenium, what other (python) library's/programs would be capable to achieve this task? With Javas Selenium it does not seem to be a problem...</p>

why this code didn't work corectly? : I have a following probleb to resolve, i don't understand why my code didnt work corectly.
Here is the problem to resolve:
Write a JavaScript function that takes as input an array of two numbers (start and end) and prints at the console a HTML table of 3 columns. The first column should hold a number num, changing from start to end. The second column should hold num*num. The third column should hold "yes" if num is Fibonacci number or "no" otherwise. The table should have header cells titled "Num", "Square" and "Fib". See the below examples.
Input
The input data comes as array of two numbers: start and end. The input data will always be valid and in the format described. There is no need to check it explicitly.
Output
Print at the console the above described table in the same format like the examples below. Don't add additional spaces. Whitespace and character casing are important, so please use the same as in the below examples.
Constraints
• The input is passed to the first JavaScript function found in your code as array of 2 elements.
• The numbers start and end are positive integers in the range [1…1 000 000] and start ≤ end.
• Allowed working time for your program: 0.2 seconds.
• Allowed memory: 16 MB.
This code is not the same by the requirement of problem, but the idea is the same I guess.
Here is my code:
<!-- begin snippet: js hide: false -->
<!-- language: lang-js -->
var fib = [];
var a, b, result;
a = 0;
b = 1;
result = b;
for (var i = 1; i < 31; i++) {
result = a + b;
a = b;
b = result;
fib.push(result);
}
console.log("<table>");
console.log("<tr><th>Num</th><th>Square</th><th>Fib</th></tr>");
var start = 2;
var end = 6;
function isFib(start, end) {
for (i = start; i < end; i++) {
fib.forEach(function (element) {
if (i === element) {
return "yes";
}
else
{
return "no";
}
});
}
}
function buildTable() {
for(var j = start; j < end; j++) {
console.log("<tr><td>" + j + "</td><td>" + j * j + "</td><td>" + isFib(start, end) + "</td></tr>");
}
}
buildTable(start, end);
<!-- end snippet -->
This code is not the same by the requirement of problem, but the idea is same i guess.

Web API optional parameters : <p>I have a controller with the following signature:</p>
<pre><code>[Route("products/filter/{apc=apc}/{xpc=xpc}/{sku=sku}")]
public IHttpActionResult Get(string apc, string xpc, int? sku)
{ ... }
</code></pre>
<p>I call this method with following URIs:</p>
<ul>
<li>~/api/products/filter?apc=AA&xpc=BB</li>
<li>~/api/products/filter?sku=7199123</li>
</ul>
<p>The first URI works without issue. The second one has a strange side effect. Even though the default values for apc and xpc should be null when not provided, the parameters are actually their names. I can overcome this by adding the additional logic:</p>
<pre><code>apc = (apc == "apc") ? null : apc;
xpc = (xpc == "xpc") ? null : xpc;
</code></pre>
<p>This seems like a hack, and would be problematic if value passed was ever equal to the parameter name. </p>
<p>Is there a way to define the Route without this side effect? </p>

jQuery On 1+ ul li href click ajax not displaying results in correct Div : I have a href link for my unordered html list. When the page loads for the first time, only the welcome page is visible as expected. When I click on the list for the first time after the page loads, I get the desired results on the desired div after clicking on the href link on the ul li. However, if i subsequently click on the other tab the results are displayed on the one i had clicked before. For example if i click on href #tab2a the results will be displayed on #tab2b nad vice versa. Ajax will direct results to the div I clicked on previously. I'm at a loss here! What could i be missing on my jQuery that will force the results to be displayed in the div that's referenced by the href id tag on unstructured list. I'm using an if else if condition. Is this the right approach?
Thank you all in advance. | 0debug |

Mac os on VirtualBox does not recognize Iphone : <p>I have been trying to connect an iPhone to Mac OS High Sierra, I've installed on VirtualBox for testing swift app I am trying to develop. However, even I connect the phone to the USB, I can't select the phone from the devices.The message in the device section says that No device connected to the mac.</p>
<p>So I have following questions,
1)Is it even possible to deploy and test iPhone app from mac os hosted on VirtualBox? and how to do it?
2)Are there any alternatives VMs to VirtualBox that allows me to connect my iPhone to virtual mac os for development purposes?</p>

Swift dispatch to overridden methods in subclass extensions : <p>overriding method signatures in extensions seems to produce unpredictable results in certain cases. The following example demonstrates two different results with a similar pattern.</p>
<pre><code>class A: UIViewController {
func doThing() {
print("dothing super class")
}
override func viewDidLoad() {
print("viewdidload superclass")
super.viewDidLoad()
}
}
class B: A { }
extension B {
override func doThing() {
print("dothing sub class")
super.doThing()
}
override func viewDidLoad() {
print("viewdidload subclass")
super.viewDidLoad()
}
}
let a: A = B()
a.doThing()
let vc: UIViewController = B()
vc.viewDidLoad()
</code></pre>
<p>This prints :</p>
<pre><code>dothing super class
viewdidload subclass
viewdidload superclass
</code></pre>
<p>You can see this skips the <code>B</code>'s implementation of <code>doThing</code> when it is cast as <code>A</code>, however includes both implementations of <code>viewDidLoad</code> when cast as <code>UIViewController</code>. Is this the expected behavior? If so, what is the reason for this?</p>

Difference between Context Managers and Decorators in Python : <p>What is the main difference between the two? I have been studying Python and came across them. A decorator is essentially a function that wraps another function and you can do anything before and after a particular function executes.</p>
<pre><code>def my_decorator(some_function):
def wrapper(*args, **kwargs):
print("Do something before the function is called")
some_function(*args, **kwargs)
print("Do something after the function is called")
return wrapper
@my_decorator
def addition(a, b):
result = a+b
print("Addition of {} and {} is {}".format(a,b,result))
</code></pre>
<p>But after studying Context Manager, I couldn't help but notice that it too has a <strong>enter</strong> and <strong>exit</strong> where you could do most similar operations. </p>
<pre><code>from contextlib import contextmanager
@contextmanager
def open_file(path, mode):
the_file = open(path, mode)
yield the_file
the_file.close()
files = []
for x in range(100000):
with open_file('foo.txt', 'w') as infile:
files.append(infile)
for f in files:
if not f.closed:
print('not closed')
</code></pre>
<p>Everything before yield is taken as part of the "enter" and everything after a part of "exit". </p>
<p>Although both Context Managers and Decorators are syntactically different, their behaviors can be looked upon as similar. So what is the difference? What are the different scenarios when one should use either of them?</p>

Returning the update value of variable initialized in a method (Android Studio) : I'm new to programming so please bare with me.
I have three methods. Method 1, Method 2 and Method 3.
Each of these methods contain a String variable which is initailized within the method. Note: These methods are called when a user clicks on a button, so in other words theres a click listener.
Now in the main method, what i want to do, is create a 4th String variable, which is initialized as such:
public class Main{
String Variable4 = variable1 + variable2 + variable 3
System.out.println(Variable4);
}
The problem however is, variable 4 is null. And this is because the variables in the 3 methods are null in the main method. But they are initialized locally in the methods.
So how would I return the initialized variable in the main method?

Inserting dynamic table values from PHP array to mysql table : Need help in inserting dynamic fields and values into mysql db table in PHP.
sampe data
$data[]=array('client'=>$clientname, 'amount' => 12000,'balance'=>6000, 'term'=>6,'maturitydate'=>'2016-05-31')
parameters passed to get the above data : branch = branchid, date =cutoffdate
Here's the table structure where I need to insert the above data.
Fields : branch
date
account_no
field
value
the first two fields values came from the parameters passed, account_no comes from the data after the querying the db using the passed param, for the field value should come from the array index and value is the index value. Been looking around the web for some possible solutions but I cannot find one.
Any help will be highly appreciated. thank you | 0debug |

"Skipped script ew223.sql",
"Script 2234ffss321.sql has an error"

<p>Is it possible to extract the scriptname with RegEx? Maybe searching for the .sql and then going recursively to the first blank before the scriptname?</p>

GET form will not echo : <p>I'm starting to learn PHP and keep getting stuck at this point after copying word for word on each guide I'm following.

calculate the distance between two cities : <p>I have a bit of what I think is an odd request. What I need to do is calculate the distance between the two cities, given their city/state/zip input data. This would be as the crow flies, rather than mileage via highways and such. And I would need miles output, i.e. x mile radius, in USA miles. </p>
<p>Again, I have city/state/zip input. Most solutions I have located are via latitude/longitude instead. Absent a city/state/zip solution, might there be a utility of some sort to convert city/state/zip input data to latitude/longitude and calculate based off of that? </p>
<p>Looking to incorporate this functionality into a .NET C#, MS SQL Server application.</p>
<p>Thanks in advance for any insight.</p>

How to integrate Ninject into ASP.NET Core 2.0 Web applications? : <p>I have found out that Ninject has recently <a href="https://www.nuget.org/packages/Ninject/3.3.0" rel="noreferrer">introduced support for .NET Standard 2.0 / .NET Core 2.0</a>.</p>
<p>However, I cannot find any extension to actually integrate it in the Web application (e.g similar to <a href="https://www.nuget.org/packages/Ninject.Web.Common/" rel="noreferrer">Ninject.Web.Common</a>)</p>
<p>Looking on the code from an old ASP.NET MVC solution, I realized that the whole mechanism is different as the classic one relied on <code>WebActivatorEx.PreApplicationStartMethod</code> and <code>WebActivatorEx.ApplicationShutdownMethodAttribute</code> which are no longer available in ASP.NET Core.</p>
<p>Also, the old <code>Ninject.Web.Common</code> assembly provided several useful classes used for initialization - Bootstrapper, OnePerRequestHttpModule, NinjectHttpModule:</p>
<pre><code>public static void Start()
{
DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
Bootstrapper.Initialize(CreateKernel);
}
</code></pre>
<p><strong>Question:</strong> is there any example of how to integrate Ninject into an ASP.NET Core 2.0 Web application?</p>

Paginate Javascript array : <p>I am trying to write a Javascript function that takes an <code>array</code>, <code>page_size</code> and <code>page_number</code> as parameters and returns an array that mimics paginated results:</p>
<pre><code>paginate: function (array, page_size, page_number) {
return result;
}
</code></pre>
<p>so for example when:</p>
<pre><code>array = [1, 2, 3, 4, 5],
page size = 2,
page_number = 2,
</code></pre>
<p>the function should return: <code>[3, 4]</code>.</p>
<p>Any ideas would be appreciated.</p>

batch if, for, do sentences : I discovered while I tried to add a function with if command that I probably don't understand the real function of theese commands.
what I tried to achieve: I tried to tell the script that "if" (variable) equals to (this) then it will "SET" (this variable) to 0
how I tried to acomplish this:
i tried to acomplish this by writing: `IF %Q%==/decrypt_Delhi-Inter-Cafe-Guest set decrypt_Delhi-Inter-Cafe-Guest=0`
and as you can see... I aparently don't understand quite what I'm doing here haha
why would i want to do something like this?
well I'm mostly playing around with some few things and in order for whatever I do to work. I need to write something that can do this (sort of same waY)
heres the script itself (i removed any unneccecary lines. between those codes theres an menu and a lot of other stuff I removed. this is the only part that needs fixing.)
(sorry for my incompetence. I'm here to learn) :P I tried to google a bit and read a lot but I had no luck sadly
set encryption_Delhi-Inter_Cafe-Guest=1
set /P Q=Console:
IF %Q%==/decrypt_Delhi-Inter-Cafe-Guest set decrypt_Delhi-Inter-Cafe-Guest=0
if encryption_Delhi-Inter_Cafe-Guest=0 goto decryptedsuccess
:decryptedsuccess
echo you successfully decrypted dheli guest network
echo encryption value: %encryption_Delhi-Inter_Cafe-Guest% | 0debug |

Select Subset of Columns based on Vector R : <p>I have a data frame with 300 columns of data.
I created a vector with 126 elements that are the column names of 126 of the 300.
I want to subset the 300 based on not being in my 126. They are NOT in order, so I can't simply remove by specifying -1:-126.</p>
<p>I tried various things with grep and matrix operations, but they did not work. Such as the following which did not work. x has 300 columns. f contains vector of 126 column names I want to exclude from x1.</p>
<pre><code>x1<-x[,-which(names(x), %in% f)]
</code></pre>
<p>If I definitively use a variable name or several, I can get it to work, but I don't want to type out the 126 elements in f. </p>

Finding merge commits from tag across branches in git : <p>My product is a plugin for IntelliJ. I support several versions of the underlying IntelliJ platform, and release builds of my plugin for each one since their APIs often change between versions. It's just me working on it, so I develop in master and then maintain a branch for each of the other versions. So my repo looks like this:</p>
<pre><code> 1.6.0 1.6.1-eap1
.... a---b---c--- master
\ \
d-------e--- idea-2017.1
\ \
f-------g--- idea-2016.3
\ \
... ... etc etc
</code></pre>
<p><code>a</code> is a stable release, and has been tagged with <code>1.6.0</code>. <code>c</code> is an EAP (beta) release, and has been tagged with <code>1.6.1-eap1</code>. This scheme works fine for these two cases.</p>
<p>Occasionally I'd like to create a dev build which doesn't go into a release channel, but that users can download manually and test out if they like. I'd like to produce a dev build for each platform, since dev users could be using any IntelliJ version. The best way I can think of would be to create a branch for the dev build from, say, tag <code>1.6.0</code> (commit <code>a</code>), and then corresponding branches from commits <code>d</code>, <code>f</code> and so on which I can merge the dev branch into and create dev builds from. </p>
<p>Assuming I want to write a script to create and maintain these branches, how can I find commits <code>d</code>, <code>f</code> and so on from the tag <code>1.6.0</code> to create the dev build branches from?</p>
