Technical interview task

	/*
	We have a two-dimensional board game involving snakes. The board has two types of squares on it: +'s represent
	impassable squares where snakes cannot go, and 0's represent squares through which snakes can move.
	Snakes can only enter on the edges of the board, and each snake can move in only one direction.
	We'd like to find the places where a snake can pass through the entire board, moving in a straight line.

	Here is an example board:

	col--> 0 1 2 3 4 5 6
