Advent of code

My participation to advent of code 2024.

Did it in zig, trying to be as memory efficient and fast as possible.

Benchmark

Done with 1000 epoch on a AMD Ryzen 7 7800X3D with a Samsung SSD 980 PRO 2TB (up to 7,000/5,100MB/s for read/write speed) on one thread.

Can be run with zig run -O ReleaseFast benchmark.zig
