Jesus Christ, seeing this I feel so stupid with my hugeass solution.
Thanks for updating the katas test cases @alaindev! I enjoyed this kata and learned a few different (and better!) ways to solve this problem from your solution and a couple others.
Very similar to this kata: http://www.codewars.com/kata/checkered-board and almost duplicate of this one: http://www.codewars.com/kata/draw-me-a-chessboard
(I'm talking about the python version)
Very easy Kata! Only 1 lambda and job done! =)
Thx for it! ;)
