This year, for my second Advent of Code, I have decided to use Rust in order to help learn the language.
For all the problems, I used rustc 1.56.1 and cargo 1.56.0, installed using rustup.
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.
