# Project Euler Solutions

This is a repository of solutions to [Project Euler](https://projecteuler.net/)
problems. All of these solutions are written by me in an attempt to fool around
with mathematics and sharpen my programming skills in a few languages.

## Rules

  - A solution is only accepted when it:
      - yields the **correct answer**.
      - takes **less than 1s** (1000ms) to compute the answer. There are some
        solutions in here that take longer, because I couldn't (yet) get them
        there.
      - is **completely written by myself**, without having looked at someone
        else's solution (unless by accident). Don't wanna spoil the fun.
      - has a **full and working testing suite**. I like my code tested.
      - **is well-documented**, meaning that when reading it, it's obvious to
        see what is going on because the variables are named smartly and there
        comments to explain what is going on when necessary.
      - is **elegant**, meaning no more complex than it should be
  - Every language needs to be treated with respect by trying to **use its
    idioms** as much as possible and by **avoiding hackery**. That's kind of the
    point of this project — getting familiar with some dope new languages and
    their cool tricks
  - Code can be shared between solutions if it helps **keeping things 
    [Dry](http://wiki.c2.com/?DontRepeatYourself)**.
  - When possible, the **standard library of the language should suffice**. I
    don't like depending on external libraries, especially when it can be useful
    to implement some things by myself. However, in some cases it's okay (for 
    example, unit testing frameworks). When possible, I'll try to bundle
    external libraries into this repository.
  - The **simpler** the solution is, in terms of lines of code and complexity,
    the better.
