Web4 Sep 2024 · First show that POSTORDER (root) will only be called once (depth 0). This is easy, since there doesn't exist a parent of root, therefore there exists no node v with v.left == root or v.right == root. Then assume that POSTORDER (v) will be called exactly once for every node at depth n, and show that this is also true for every vertex at depth n + 1.
