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):

1
2
3
4
5
. O . X .
 . X X O .
  O O O X .
   . X O X O
    X O O O X

"Player 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 won since O didn't connect top and bottom.

Setup

Go through the setup instructions for ECMAScript to install the necessary dependencies:

http://exercism.io/languages/ecmascript/installation

Requirements

Install assignment dependencies:

1
$ npm install

Making the test suite pass

Execute the tests with:

1
$ npm test

In the test suites all tests but the first have been skipped.

Once you get a test passing, you can enable the next one by changing xtest to test.
