Advent of Code 2021

This year, for my second Advent of Code, I have decided to use Rust in order to help learn the language.

Execution Environment

For all the problems, I used rustc 1.56.1 and cargo 1.56.0, installed using rustup.

How to Use

First, all solutions must be built, using cargo build.

All solutions expect input on stdin. Call them like so: cargo run -q --bin dayX-partY < inputs/dayX > output to obtain the output in a file.
