AoC readme says that:
every problem has a solution that completes in at most 15 seconds on ten-year-old hardware
It happens that one of my computers runs on roughly 10 years old Intel i5-4690k so I decided to use it as a benchmarking machine instead of my daily driver i9-10850k that runs at almost twice the clock.
