Binary Tree Postorder Traversal in Python - TutorialsPoint

WebTo find the boundary, search for the index of the root node in the inorder sequence. All keys before the root node in the inorder sequence become part of the left subtree, and all keys after the root node become part of the right subtree. Repeat this recursively for all nodes in the tree and construct the tree in the process. WebMay 26, 2024 · Python Server Side Programming Programming. Suppose we have a binary tree. We have to find the post order traversal of this tree using the iterative approach. So if the tree is like −.
