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 ranks are: "A" (Ace), "K" (King), "Q" (Queen), "J" (Jack), "T" (Ten), and "9" to "2".
The descending suits are "h" (hearts), "d" (diamonds), "c" (clubs), "s" (spades).
Texas holdem uses the classical poker hand list: Straight flush, Four of a kind, Full house, Flush, Straight, Three of a kind, Two Pair, One Pair and High card.
Because of the presence of community cards in Texas hold 'em, different players' hands can often come very close in value. As a result, it is common for kickers to be used to determine the winning hand for cases where two or more hands tie. A kicker is a card which is part of the five-card poker hand, but is not used in determining a hand's rank. For instance, in the hand A-A-A-K-Q, the king and queen are kickers.
In our version of Texas Hold'em cards of differing suits have different values. This means that there is only ever one best five-card hand to return. So "Td" is higher than "Tc", but lower then "Jc".
Your goal is to choose the best hand with 5 cards and return them as a string, where cards are separated by commas and ordering from the highest to lowest value. For example: We have two pair by queens (heart and spades) and eights (diamonds and clubs) and nine heart as a kicker. The result: "Qh,Qs,9h,8d,8c". Be careful with order.
Input: A list of cards as a string.
Output: The best hand as a string.
How it is used: This concept is a good example of combinatorial optimisation process, and could come in handy should you make a poker game in Python.
cards_quantity == 7 All cards correct and unique.
