Today was surprisingly pleasant for me.
My part 1 solution was still a bit messy but I was able to nicely generalize in part 2 and I'm really pleased with my solution.
Also while I initially thought immutability would be really annoying for this, the immutability as a core part of Roc surprisingly aided me with the solution in the end.

I am not a fan of my part2. In the end, it was a lot of try and error until the test pass
