Credits to @mykl@lemmy.world for the approach of using reduce and also how to split the input by multiple characters.
I can happily say that I learned quite a bit today, even though the first part made me frustrated enough that I went searching for other approaches ^^
Part two just needed a simple modification. Changing how the input is parsed and passed to the adapted function took longer than changing the function itself actually.
