Advent of code 2024

My solutions for the 2024 Advent of Code event. All solutions are written in Rust, and are of questionable quality since it's my first time using the language. The code is reasonably performant however and solves all problems in ~140 ms (see benchmarks below).

Requirements

• Rust (I used 1.79.0 but other versions should work)
• The aocd python library (pip install aocd)
• A session token from AoC (export AOC_SESSION=<your session token>)

Inputs

AoC problems require (personal) AoC inputs, and the AoC creator has requested that they not be shared publicly (hence why they are not in this repo). Instead, use the get_inputs.py script to download all inputs into the inputs directory prior to running the rust code. The script assumes you have exported your session token as an environment variable.

Running solutions

Run either

• ./run.sh to run all days and get a benchark for the runtime or
• ./run.sh dayx to run a specific day (e.g. ./run.sh day1)
