Connect in Ruby
Compute the result for a game of Hex / Polygon
exercism fetch ruby 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.
For installation and learning resources, refer to the exercism help page.
For running the tests provided, you will need the Minitest gem. Open a terminal window and run the following command to install minitest:
gem install minitest
If you would like color output, you can
require 'minitest/pride' in
the test file, or note the alternative instruction, below, for running
the test file.
Run the tests from the exercise directory using the following command:
To include color from the command line:
ruby -r minitest/pride connect_test.rb
