Solution to the n-Queen puzzle (https://en.wikipedia.org/wiki/Eight_queens_puzzle)

	def nQueens(n: Int) = (0 until n).permutations filter {p =>
	val i = p.zipWithIndex.toSet // p[i] is the column of the queen on ith row (must be a permutation of 0 until n)
	i.map{case (c, d) => c + d}.size == n && // No 2 queens can have same col + diag
	i.map{case (c, d) => c - d}.size == n // No 2 queens can have same col - diag
	}

	for {
	(solution, num) <- nQueens(8).zipWithIndex
	_ = println(s"Solution #${num + 1}:")
	col <- solution
