Advent of Code

Over the past weeks, I've been working through Advent of Code. If you haven't seen it, it's basically a daily programming challenge - one a day for the 25 days running up to Christmas.

The challenges open at 00:00 EST (so, 05:00 GMT) so if you want to have a crack at the leaderboard, it's a very early start. The best I've managed so far is about 162nd, but there's a few days left.
