Advent of Code 2020

My solutions for Advent of Code 2020.

Planning to do this year in Rust, we'll see if I run out of steam!

Input for each day goes in input/<day>.

The binary for each day can be run with cargo run --bin <day>. This will output the solutions for part 1 and part 2.

Unit tests can be run with cargo test --bin <day>.
