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.
Sometimes it is necessary to raise an exception. When you do this, you should include a meaningful error message to indicate what the source of the error is. This makes your code more readable and helps significantly with debugging. Not every exercise will require you to raise an exception, but for those that do, the tests will only pass if you include a message.
To raise a message with an exception, just write it as an argument to the exception type. For example, instead of
raise Exception, you shold write:
raise Exception("Meaningful message indicating the source of the error")
