About this Kata

This kata is blatantly stolen from acm.uva.es/p/v103/10315.html It is a subset of KataTexasHoldEm , which is a very large Kata.

Problem Description

Your job is to compare several pairs of poker hands and to indicate which, if either, has a higher rank.

Poker rules description

A poker deck contains 52 cards - each card has a suit which is one of clubs, diamonds, hearts, or spades (denoted C, D, H, and S in the input data). Each card also has a value which is one of 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, ace (denoted 2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K, A). For scoring purposes, the suits are unordered while the values are ordered as given above, with 2 being the lowest and ace the highest value.

A poker hand consists of 5 cards dealt from the deck. Poker hands are ranked by the following partial order from lowest to highest.

Suggested Test Cases

Sample input:

Black: 2H 3D 5S 9C KD  White: 2C 3H 4S 8C AH
Black: 2H 4S 4C 2D 4H  White: 2S 8S AS QS 3S
Black: 2H 3D 5S 9C KD  White: 2C 3H 4S 8C KH
Black: 2H 3D 5S 9C KD  White: 2D 3H 5C 9S KH

Each row of input is a game with two players. The first five cards belong to the player named “Black” and the second five cards belong to the player named “White”.

Sample output:

White wins. - with high card: Ace 
Black wins. - with full house: 4 over 2 
Black wins. - with high card: King
Tie.

Comments from those who are working on this Kata

I found a reference to this Kata on IvanSanchez blog: isanchez.net/2009/04/19/ruby-coding-dojo-this-week/

The 3d rows should result in Black winning, not White since 2H 3D 5S 9C KD is higher than 2C 3H 4S 8C KH
