🎄 Advent of Code 2020 🎄

Run

$ cargo run --release --bin <xx>

and replace <xx> by the day number, e.g. 05, or 17.

Some solutions use new Rust features not yet available in the stable release. They can be recognized by the following error:

error[E0554]: `#![feature]` may not be used on the stable release channel

If you see this error you need compile using the nightly toolchain of Rust:

$ cargo +nightly run --release --bin <xx>

The last column contains improved solutions inspired by solutions of other people.
