Advent of Code solutions

Solutions to Advent of Code problems 2021 in Rust.

$ cat src/year2021/day01_input.txt | cargo run -q 1 2

• Create a file day01.rs under src/year2021;
• Add a function pub fn solve(input: &mut Input) -> Result<u32, String> under that file;
• Export the function in src/year2021/mod.rs;
