Iterative approach for postorder traversal
Web4 feb. 2024 · 1. In-Order Traversal. In in-order traversal, we traverse the left child and its sub-tree (s), then we visit the root and then traverse the right child and its sub-tree (s). It takes a “left-root-right” order. Before we take a look at a code sample for this algorithm, let’s try to outline the steps involved: Web27 nov. 2016 · Given a binary tree, write an iterative and recursive solution to traverse the tree using postorder traversal in C++, Java, and Python. Unlike linked lists, one …
