aoc2022 VS advent-of-code-2022

I was also learning C# this time, and performance wise it's better than expected (for a VM language of course) but can't really compete in problems like day 23 or 16. I think I squeezed what I could out of the less optimised problems today and even now these two make about 50% of the total. Repo for reference.

C# , around 200 µs each part

C# 1ms / 15 ms

C# w/Raylib source

C#

... In any case, ended up with way more lines than should be pasted here (or necessary): goto github

C# + raylib

nice one! you can make it even faster by creating a compile time multiplication table as i have done here, so all that happens at runtime is the bucketing of similarly aged fish, 7 multiplications + a sum

you've still got some overhead in your code, my rust solution creates a dense lookup array at runtime & takes ~200us on my 10850k. are you including file IO and printing to stdout?
