The first days of #AdventOfCode are supposed to be easy. So, of course, I am over engineering to aim for best performance #rustlang
If you want to prepare for this year's #AdventOfCode, take a look at my article on dynamic programming, it will probably be useful for some of the later puzzles! qsantos.fr/2024/01/04/d...
