Advent of Code in Zig

Implementing Advent of Code 2024 in Zig.

Disclaimer: This is the first time I've written Zig so it's probably not using best practices and whatnot. Any helpful feedback welcome 😎

Getting started

First, Install zig, e.g. brew install zig.

To run a particular day challenge:

# In debug mode
zig run src/main.zig -- <day n#>

# In release mode
zig build -Doptimize=ReleaseFast
./zig-out/bin/aoc24 <day n#>

Benchmarks

Benchmarks from running on my M3 Pro:

Challenge	Status	Time (mean ± σ)	Range (min … max)	Details
#1	Done	8.1 ms ± 0.5 ms	3.5 ms … 22.3 ms	User: 2.0 ms, System: 5.7 ms, Runs: 353
