-- Mark Twain
Texas hold'em is a variation of the standard card game of poker. Two cards (hole cards) are dealt face down to each player and then five community cards are placed face-up by the dealer. And when all openings we need to define what is the combination a player have.
You are given a sequence of 7 cards and you should choose the best hand (5 cards) in it. Card sequence are described as a string, where each card are defined by two character - rank and suit. Cards separated by commas.
The descending suits are "h" (hearts), "d" (diamonds), "c" (clubs), "s" (spades).
