# Advent of Code solutions
In zig, cause we gotta go fast B)
Run code with `zig build run -Doptimize=ReleaseFast`
# Timings
Measurements are taken from an average of 100 runs on my Ryzen 5950x processor
(~4.2GHz) I compile everything with -OReleaseFast
Every day is programmed as a function that receives a string and returns a pair
of ints. This is what is measured, I decided not to include file I/O in the benchmarks because it causes a lot of variance and is not very interesting (imho) to optimize.
