Binary tree traversal without recursion
WebIn recursive DFS traversal of binary tree, we have three basic elements to traverse: root node, left subtree, and right subtree. Each traversal process nodes in a different order using recursion, where recursive code is … WebHere is a general purpose tree traversal implementation that doesn't use recursion: ...

WebJul 30, 2024 · Preorder Traversal in Binary Tree Iteratively (without recursion) In this article, we are going to find what preorder traversal of a Binary Tree is and how to implement preorder traversal iteratively without using recursion? We have provided the implementation in C++. Submitted by Radib Kar, on July 30, 2024 WebIn this method, we have to use a new data structure-Threaded Binary Tree, and the strategy is as follows: Step 1: Initialize current as root Step 2: While current is not NULL, If current does not have left child a. Add current’s value b. Go to the right, i.e., current = current.right Else a.
WebWe can perform Inorder Tree Traversal without Recursion in C in two ways, First we can use stack and other one is iterative method known as morris traversal. In given example we are using stack method to perform inorder traversal on tree. Inorder traversal of tree is Left->Root->Right.
