This wasn't too bad. Had a worried moment when the part 2 solution took more than half a second. Maybe a better solution that brute forcing all the joker combinations, but it worked.
Python
I barely registered a difference between part 1 and part 2.
I suppose it took about 3.5 times as long, but I didn't notice :P
Edit: I realize that I made the implicit assumption in my solution that it doesn't make sense to have multiple jokers be interpreted as different values. i.e., The hand with the maximum value will have all Jokers interpreted as the same other card. I think that is true though. It worked out for me anyway.
Yea I was thinking there might be a simplification trick, but also figured "there can't be that many combinations right?" I suspect that was probably an intended optimisation.
I think one doesn't need to generate all combinations. All combinations using cards already present in the hand should be enough (since a joker can only increase the value of the hand by being grouped with existing cards (since in this game having four of a kind is always better than having any hand with a four of a kind/full house and having 3 is always better than any hand with pairs, and having a pair is better than any card without any cards of the same kind)). This massively decreases the amount of combinations needed to be generated per jokery hand.
