I am a beginner in programming, especially Python. I got the answer for the problem, but how can I optimize it?
A Pythagorean triplet is a set of three natural numbers, a < b < c,
for which,
a2 + b2 = c2 For example, 32 + 42 = 9 + 16 = 25 = 52.
There exists exactly one Pythagorean...
I am still new to c++ and don't have a great insight on my coding yet, so I would be very grateful to anyone and everyone that gives advice.
Also, this code is meant to: keep all of my objects in an ordered fashion based on depth. I have a couple functions that allow for easy management and I ma...
I would be glad if someone takes a look at my code and maybe improves it. I wouldn't mind if it would run with jQuery. I uploaded it on jsbin.com. It's all about the effect and not about encryption or decryption.
I've written the following JS Code:

I have a problem. This code works great, but i think it can be reduced.

This is my first attempt at a weekend-challenge. I would prefer if reviews contained suggestions on how to improve the algorithm, but all suggestions are acceptable.
Here is the code:
#include <stdio.h>
int isAvailable(int sudoku[][9], int row, int col, int num)

int rowStart = (row/3) *...
This is my first, very-very first attempt at java. I haven't started tackling the actual resolution of the sudoku puzzle (not even sure where to start, haven't looked at other weekend-challenge entries yet). I don't have much to go over here, but I'm sure it's filled with beginner mistakes alread...

Even though it's the first time I'm writing something this "big", it feels like I know C# quite good. It's been nice to learn LINQ also and I am very impressed by the features, and perhaps I have overused it here (if it's possible to do that).
