This year’s Advent of Code is just around the corner! I had a lot of fun with these puzzles last year, so in honor of the occasion I thought I would share some of the things I learned over the course of the challenge. For the unfamiliar, Advent of Code is an Advent calendar where a new programming puzzle unlocks each day of December (from the 1st through the 25th). Each puzzle has a part 1 and a part 2, where part 2 is usually a more complicated variation on the first part.
