Five of a kind is a hand that contains five cards of one rank, such as five
threes. It ranks above a straight flush but is only possible when using one or
more wild cards, as there are only four cards of each rank in the deck.
So the answer is 0 if you're not using any wild cards. If you're using wild
cards, the answer would be different for different numbers of wild cards, and
whether jokers are being used as wild cards.
