We traverse the tree and try to go to the left most node. Here, Leftmost item is 8, right item : 9, middle item : 4 (Now recursive moving in the tree) Print 8 9 4. Leftmost item is 4 (However, we’ve visited it already), so now, right item is 5 then middle item : 2. Print 5 2.

How PostOrder traversal of Binary tree works? - EduCBA

WebIn computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited. Web5 Oct 2014 · Post-order traversal is defined as follows:- Traverse the left sub-tree in post-order. (Step 1) Traverse the right sub-tree in post-order. (Step 2) Visit the root The post-order traversal can then be defined in this way – The nodes of the tree will therefore be in order – 4, 5, 2, 6, 7, 3, 1 The recursive version can be written as:- 1 2 3 4 5 6 7 8 Web31 Mar 2024 · 2) Postorder traversal using two Stacks. Approach 1 The approach used is based on using an unordered set to keep track of visited nodes and a while loop to traverse the tree.
