Anybody knows a 'C' code contest which is easier to participate by internet?

I have created a 'C' program with its pseudocode which generates a 'Magic Square' for any given integer between 2 and 101,all on my own. Ofcourse, I'd obtained the bare logics to do this from the internet. I've heard that this square has many significant applications in various technological fields! Could you please suggest if there is any use of programs which have their logics inherited from an unknown source? Also do you know how can I register this pseudocode or participate in a 'C' code contest which entertains remote participation? And for those who dont know whats this square is... " A Magic Square of order 'n' is a square matrix containing distinct integers from 1 to (n*n) arranged in such a way that the sum of 'n' numbers in any vertical, horizantal or main diagonal lines is always the same number called the 'Magic Constant'.
