Inorder Traversal

Iterative inorder tree traversal

Inorder tree traversal is very useful and quickly finds the tree’s balance. When we use inorder tree traversal, we start by recursively visiting the left subtree first. After that, we visit the root and then the right subtree. Each node stores a value, and we know this value as the key. In inorder tree traversal, the output produces sorted key values in ascending order.

First, let’s look at inorder tree traversal using iteration.
