# 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](https://adventofcode.com/2020/), 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```
