Below is a listing of my solutions to Project Euler problems. Some of the solutions are good and some are just quick hacks.

I’ve put up my own solutions because I always enjoy reading other people’s code and it’s possible someone can learn something useful from my code.

I’d suggest not using my code for the answers because you won’t learn much. If you’re stuck on a problem you might look at my code for a little hint or something but it’s much more rewarding to find the solution for yourself. :)
