Advent of Code Solutions

I have set myself a personal challenge to try and get up to date with advent of code, a set of programming challenges released each December.

Each day has 2 related problems, for a total of 50 problems per year. Each button below will show my code solving that problem. Green buttons where I have solved both problems of the day, orange where I have only solved the first one and red where I haven't solved either.
