Solutions to the problems at ProjectEuler.net

I recommend that everyone attempt to solve these problems on their own before viewing the solutions here. This repository is for the sharing and comparison of solutions.

###INSTRUCTIONS

Currently, all solutions are inside the python package 'solutions'. To run a solution for problem x use python -m solutions.Problem<x>.solve from the root of the repository

###Note: Some solutions use the utils.primes module and may require a 'primes' file in the working directory. If this file is not present, the primes module will generate it automatically. Currently it will generate all primes less than 2,000,000. This will only take maybe a few seconds on modern systems and uses around 12 MB of space.
