Here lies my solutions to AoC's that I've participated in.

From its site:
Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.
For me, it's a way to try out new technologies; for example picking up new languages like Nim and Clojure.
Or a way to approach common problems in a totally different manner; for example using functional programming to solve problems or implementing solutions more efficiently by utilizing SIMD instructions or parallelism.
