The instructions for part 2 are missing info about how to handle the Four Of A Kind and a joker case. Wasted quite some time because I assumed that the remaining joker would remain unused, but turns out it turns your deck into Five Of A Kind.
Did everybody else just expect this?
Oh oh, you’re correct :( How did I not notice that; guess too much thinking about standard card games, plus no hand in the example input is a Five Of A Kind.
