Web27 Aug 2024 · For postOrder, we are looking to traverse in following way: Copy left -> right -> root So, if we're at any node it means it's left and right subtree has already been explored. That means we need to look at the parent for successor. If we're reaching the parent from it's right child, that means parent itself is successor, by the definition in #1 Web24 Feb 2024 · depiction of the guide tree. B.
