## 🎄 Advent of Code 2015-2023 🎄

These are Rust-language solutions for the [coding-challenge advent

calendar](http://adventofcode.com/).  You'll need stable Rust 1.65 and Cargo to

run.

The code for the different years is in the respective subdirectories.

I've tried to make the solutions small and somewhat optimized for speed (so far,

no solution takes more than about a second on an up-to-date machine).  Inputs

are included in text file form and parsed.

### External code used

A custom helper library is used, called `advtools`.  It provides utilities for

easily parsing the input files, which I don't want to rewrite each year, and

access to often used external crates like itertools and rayon.

For tasks that require nontrivial datastructures or algorithms, I try to find

and use a third-party crate to show off the ease of using Rust's crates

infrastructures, e.g. `petgraph`.

### Building

All code is contained in a single Cargo workspace, with a different binary

target for each day.  Solutions are printed to stdout.

A simple Makefile is also provided in order to run all years and/or days.  Just

run `make` to run everything, or e.g. `make 2022` to run only one year.

### `advtools`

This subdirectory contains a library I've developed over time to ease

boilerplate and keep utilities for common tasks, such as manipulation of things

on grids.  It is also released under that name to `crates.io`.
