Advent of Code 2020 solutions

A set of 25 puzzle inputs and 50 puzzle solutions, two for each day. Most of these were written within an hour of the puzzle's release. The puzzles can be found here, although only the first one is visible until you solve it.

Most solutions output just two lines, the answers to part 1 and 2, but some provide more information or a rudimentary animation.

Run a solution by passing the input as an argument:

./four.py input4

Or via the standard input:

./fifteen.awk <input15
