These are my solutions to Advent of Code 2019, written in Rust.

To build you will need Cargo. The easiest way to install this is to use rustup.

To just build, run cargo build, or cargo build --release for optimizations. These will produce an executable binary for each day in ./target/debug/ or ./target/release/ respectively.

Alternatively, you can just use cargo run --bin dayXX to run a given day XX.

Note that each day takes input from stdin.

For example, to run day 1 on the input, run:

cat input/1.txt | cargo run --bin day01
