WebA backtracking algorithm begins with an empty solution and extends the solution step by step. The search recursively goes through all different ways how a solution can be constructed. Since the bounds are small, we can recursively backtrack over all ways to place the queens, storing the current state of the board. http://panonclearance.com/given-a-directed-graph-use-backtracking-to-generate-all
