WebAlgorithm for PostOrder traversal implementation Step 1: Traverse the left subtree, i.e., traverse recursively. Step 2: Traverse the right subtree, i.e., traverse recursively. Step 3: Finally, visit the root node. PostOrder traversal is useful to get the postfix of an expression in a Binary tree. WebPost-order Traversal In this traversal method, the root node is visited last, hence the name. First, we traverse the left subtree, then the right subtree and finally the root node. In the below python program, we use the Node class to create place holders for the root node as well as the left and right nodes. chip google fire tablet

"WebTraversal is a process to visit all the nodes of a tree and may print their values too. Because, all nodes are connected via edges (links) we always start from the root (head) node. That is, we cannot randomly access a node in a tree. There are three ways which we use to traverse a tree − In-order Traversal Pre-order Traversal Post-order Traversal " - Binary tree postorder traversal python
