Iterative post order traversal without keeping visited flag

WebThe key to doing DFS iteratively and still having pre-order/post-order operations is to NOT just append every child at once, but instead, behave exactly as recursive DFS would, which is adding just one child-node to the stack at a time, and only removing them from the stack once it has finished.
