# Advent of Code 2020
## Completion
Day 12 is missing because I did it in IPython and never bothered putting it in a source file, probably.

## Benchmarks (Rust)
I'm somewhat trying to do the <1 second challenge, but I've been a bit short on time (and willpower), and I'm just faster at solving challenges in Python. Anyway, here's my benchmarks (ran on my mostly idle server):
