My solutions to the programming puzzles on Advent of Code.
Solutions are written in Ruby.
As of late December 2015, I decided to learn a bit about Go and redo the puzzles! My solutions in Go can be found here.
"Advent of Code is a series of small programming puzzles for a variety of skill levels. They are self-contained and are just as appropriate for an expert who wants to stay sharp as they are for a beginner who is just learning to code. Each puzzle calls upon different skills and has two parts that build on a theme."
