Inorder Traversal Of A Binary Tree
A Quick Overview
A tree can be traversed in various ways, unlike linear data structures (Stacks, Linked Lists, Arrays, Queues, etc.) where there is only one logical way to traverse them.
Introduction to Inorder Traversal
It’s a technique of traversing over all nodes of tree. During in-order traversal of a binary tree, we traverse whole left subtree, then current node, and then the right subtree.
Check Out Examples
1. Traverse left subtree, i.e., call Inorder(left->subtree)
2. Visit the root.
3. Traverse right subtree, i.e., call Inorder(right->subtree)
O(N), where N is no of nodes in tree.
This method traverses the trees iteratively. This requires stack data structures.
