So In a recent project I had need for some inventory management.
I decided to create a custom struct for managing the concept of a number range.
It allows for easy navigation of a collection.
It function similar to .net's own Enumeration classes, with extension methods, wrapper classes and ...
To learn Scala, coming from Java and Python, I'm attempting to program an implementation of Conway's Game of Life.
I've implemented two different approaches so far, with the first being so bad I'm not even going to ask for review.
The second is a bit cleaner, and produces the correct output, bu...
I wrote this solution to contest challenge and I am new to D and was hoping for some tips to make it faster or more Dish.

I want to implement infinite rotation animation.
I thought it would work with UIView.animateWithDuration with trailing recursion.
But it's getting slower and slower on simulator.
I've checked that memory usage is not increasing.
I want to know what's slowing down the performance and how to...
Consider we have more than one user controls in a form. each one of them have some controls like TextBox, Button, ... inside it. Suppose changing a property of a control in User Control A change a property of some other control in User Control B.
I just Write this code for User Control A:

I am an absolute newbie to Python and humbly apologize if this is too trivial an issue. I have developed the below code to generate Fibonacci numbers by reading input from a file :-
import sys
def fibonacci(limit) :
sum=count=0
a=0
b=1
#fib: 0 1 1 2 3 5 8 13 21 34 55 89 144
#count:0 1 2 3 4 5 ...
Hi I need some help with my js code. The jquery code is for html5 video event GA tracking and I want to make it a little bit more shorter and cleaner. The code works I am getting all the events but would like to make it more simple.
Code below

console.log("Finished");

Please look the code below

int length;
int i;
int a[100];
int high;

I tested your code, like so:
int r=0,c=1;
Deque<Integer> list = new ArrayDeque<>(1501);
list.add(500);
for (int x = 0; x < 500; x++)
{
list.add(50);
list.add(50);
list.add(15);
}
long start = System.nanoTime();
int t=list.pop();
for(int i=0;i<t;i++){
int a=list.pop()...
So I am very new at coding, but I really have no idea why this is not working.
<code>
class HelloWorld {
public static void main(String[] args){
System.out.println("Hello World!");
}
}

I created the .java file using Notepad++ then I went into my cmd and located the file (using ...
Is the code part in the finally block well handeled or should I do it in another, more cleaner way.

I've been learning a lot about functional programming lately and I've recently started learning Haskell to which I'm very new.
I've written a simple number guessing game and I would like to have feedback on what is good or bad about my code and how it could be improved.

Do not use int for flag. Use bool or enum
Do not use string for status. Use bool
Do not use object[] for astatus. Write own class for that

On the journey of learning software design I am now taking a slightly different approach and thinking to focus on some real world projects. After code reviews I would be publishing them to the opensource community. So, I got inspired by this repo and I would agree that I took the majority of the ...
I did an assessment task where I had to implement the game snap. The description:
Simulate a simplified game of snap between two computer players using N packs of cards (standard 52 card, 4 suit packs). A game of snap proceeds by shuffling N packs of cards and then drawing cards from the top of ...
Is the following way to convert a primitive long to String a good approach?
long longAbc = 123l;
String longString = longAbc + "";
Is this recommended? Or is the following approach better?
Long longObject = longAbc;
String longString = longObject.toString();
This interesting idea came up when I was designing the for_each for tuple-like objects in this post. The for_each in that post makes it possible to write code like:
auto t = std::make_tuple(42, 'c', 3.14);
for_each(t, [](auto x) { std::cout << x << '\n'; });
But unfortunately, this way we can ...
What do you think about this implementation of 2 floats comparison functor considering how tolerance is introduced?
