This is an iterative process.The CODE link is as follows:-COD 2020-10-28 3. Binary Tree PostOrder Traversal. In a PostOrder traversal, the nodes are traversed according to the following sequence from any given node: If a left child exists, it will always go to it first. After visiting the left sub-tree, it will then move to its right sub-tree. After it visits the right sub-tree, it … If we employ the pre-order traversal to this example above, here is how the tree is sequentially visited: 7 -> 3 -> 2 -> 6 -> 9 -> 8 -> 14. Here we just change the order of the visit, in this traversal, the root of the tree always is visited first before any recursion, here is our code for this implementation: Postorder Traversal: Given a binary tree, return the postorder traversal of its nodes’ values.
Postorder traversal is one of the depth first tree traversal methods.
Iterative Postorder Traversal Using Two Stacks - TutorialCup
Postorder traversal is a depth-first tree traversal algorithm. In depth-first traversal, we start at the root node and then we explore a branch of the tree till the end and then we backtrack and traverse another branch.

Postorder traversal 5->6->12->9->1-> In the above example, we have implemented the tree data structure in Java. Here, we are performing the postorder traversal of the tree.
Traverse the right subtree in PostOrder. Postorder traversal in binary tree | Data structures YASH PAL June 04, 2020 In postorder traversal, we first traverse the left subtree of the root node and then the right subtree of the root node, and then we traverse the root node of the binary tree. Properties of postorder traversing
Postorder Traversal — In Postorder Traversal root node is visited after it’s left and right child. Level order Traversal — In Level order Traversal, all the nodes present in same level is visited first and then their children will be visited. In this article, we are going to talk about the Postorder Traversal. Postorder traversal is used to delete the tree. Please see the question for deletion of tree for details.

Postorder traversal is also useful to get the postfix expression of an expression tree. Please see http://en.wikipedia.org/wiki/Reverse_Polish_notation to for the usage of postfix expression. In last two posts, iterative inorderand iterative preordertraversal, we learned how stack can be used to replace recursion and why recursive implementation can be dangerous in production environment. In this post, let’s discuss iterative postorder traversal of binary tree which is most complex of all traversals.

Binary tree traversal: Preorder, Inorder, Postorder. mycodeschool. mycodeschool.
Unlike other linear data structures, where we traverse through every element in order, it’s not the same with the tree. Here, the Postorder name itself suggests that the root node of the tree would be traversed at the last. Let's understand the Postorder traversal through an example. Consider the below tree for the Postorder traversal.
