My clojure solutions and explanations for the programming problems found at https://projecteuler.net/
I found out about Project Euler from this article: http://www.makeuseof.com/tag/4-reasons-shouldnt-learn-code-codeacademy/
I was doing courses on codecademy at the time, and this is what I saw... I was very happy with codecademy at the time, but I thought I'd read it anyhow just to see what it had to say. Well... now I happen to agree.
Project Euler... an awesome way to REALLY learn to program!
