Advent of Code 2023 in Go

Solving Advent of Code for fun.

Expect messy code and ocasional refactors.

Structure

Every day has a numbered folder followed by a hyphen and a more descriptive name. Tests inputs and the main input are stored in text files. There is a main.go file that has a CLI for computing the outputs, and each part of the problem is usually in its own file inside a function just like this:

func part1(input io.Reader) (output int32) {
    // output type varies
}

Along side any other helper functions. This makes them easier to test with Go's builtin support for unit tests.
