When we visit a node, we print its value, and then we want to visit the left child followed by the right child. The fundamental problem we face in this scenario is that there is no way that we can move from a child to a parent.

WebJul 30, 2024 · In the earlier article on preorder traversal, we saw that preorder traversal is one of traversal which is based on depth-first search traversal. The basic concept for preorder traversal lies behind its name. "pre" means first/before and that's why the root is traversed before its left &amp; right subtree. The basic rule is: First, traverse the root WebJun 17, 2024 · Iterative Preorder Traversal. Given a Binary Tree, write an iterative function to print the Preorder traversal of the given binary tree.
