In the card game poker, a hand consists of five cards and are ranked, from
lowest to highest, in the following way:
High Card: Highest value card.
One Pair: Two cards of the same value.
Two Pairs: Two different pairs.
Three of a Kind: Three cards of the same value.
Straight: All cards are consecutive values.
Flush: All cards of the same suit.
Full House: Three of a kind and a pair.
Four of a Kind: Four cards of the same value.
Straight Flush: All cards are consecutive values of same suit.
Royal Flush: Ten, Jack, Queen, King, Ace, in same suit.
The cards are valued in the order:
2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace.
If two players have the same ranked hands then the rank made up of the
highest value wins; for example, a pair of eights beats a pair of fives (see
example 1 below). But if two ranks tie, for example, both players have a pair
of queens, then highest cards in each hand are compared (see example 4
below); if the highest cards tie then the next highest cards are compared, and
so on.
Attached is a file that contains one-thousand random hands dealt to two
players. Each line of the file contains ten cards (separated by a single space):
the first five are Player 1's cards and the last five are Player 2's cards. You can
assume that all hands are valid (no invalid characters or repeated cards), each
player's hand is in no specific order, and in each hand there is a clear winner.
My app showcases all the hands, what hand each
player had and who won for each. There is a tally for the total number of
wins for each player. To run the program, just type ruby poker.rb in the terminal!
