Language: Rust

Every day has a dedicated file in the solutions directory, and two inputs (one the actual input, another the example suffixed with 'e') in the inputs directory.

Different people have different ways of approaching Advent of Code. Mine is not competitive. Instead, I'm just trying to explore rust while having some fun. Many of these solutions can be briefer, even in Rust, but I'm trying to keep them as readable as possible.

I try to solve these problem within the bound of the standard library. However, the standard library is limited compared to many other languages. Things like regex, mundane mathematical operations, parallelism are absent. Therefore, I'm using a few external libraries.

Currently I'm using:

• regex for regex
• rayon for parallelism
• num for mathematical operations
• derive_deref because implementing deref is tediously trivial
• indexmap because doing it by hand is tedious

Shamelessly stole and adapted the scaffolding mechanism found here to my need.
