Connect in PHP
Compute the result for a game of Hex / Polygon
exercism fetch php connect
Compute the result for a game of Hex / Polygon.
The abstract boardgame known as Hex / Polygon / CON-TAC-TIX is quite simple in rules, though complex in practice. Two players place stones on a rhombus with hexagonal fields. The player to connect his/her stones to the opposite side first wins. The four sides of the rhombus are divided between the two players (i.e. one player gets assigned a side and the side directly opposite it and the other player gets assigned the two other sides).
Your goal is to build a program that given a simple representation of a board computes the winner (or lack thereof). Note that all games need not be "fair". (For example, players may have mismatched piece counts.)
The boards look like this (with spaces added for readability, which won't be in the representation passed to your code):
O" plays from top to bottom, "Player
X" plays from left to right. In
the above example
O has made a connection from left to right but nobody has
O didn't connect top and bottom.
Running the tests
Go to the root of your PHP exercise directory, which is
<EXERCISM_WORKSPACE>/php. To find the Exercism workspace run
% exercism debug | grep Workspace
Get PHPUnit if you don't have it already.
Execute the tests:
% ./phpunit.phar connect/connect_test.php
