This are my solutions to the problems in the webpage of project euler (http://projecteuler.net/). Before you go in to the code, I recommend that you really try to solve the problems by yourself.
I will try to find the optimal solution, but hey... I am not perfect ;) iy ou think that my algorithm can be optimized, let me know.
All the files here are in the public domain and you can do with them as you please :)
