The postorder traversal of a binary search tree involves visiting each of the nodes in the tree in the order (Left, Right, Root). An example of postorder traversal of a binary tree is as follows. A binary tree is given as follows.

Here is a … 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 WebListing 2 shows a version of the preorder traversal written as an external function that takes a binary tree as a parameter. The external function is particularly elegant because our base case is simply to check if the tree exists. If the tree parameter is None , then the function returns without taking any action.
