InOrder traversal of binary tree implementation in Java

By | July 15, 2020

This post talks about InOrder traversal of binary tree implementation in Java

In InOrder traversal, the root is visited between the subtrees

InOrder traversal is defined as follows:

  • Traverse the Left Subtree
  • Visit the root
  • Traverse the Right Subtree

Binary Tree For Traversal

InOrder, traversal can be implemented either recursive and iterative approach. Both Approaches have shown below:

Recursive Approach:

Time Complexity: O(n) and Space Complexity: O(n)

Non-Recursive Approach:

The non-recursive version of InOrder traversal is similar to preorder. The only change is instead of processing the node before going to the left subtree, process it after popping.which is indicated after completion of left subtree processing. 

Time Complexity: O(n) and Space Complexity: O(n)

Below is the Complete Source code:
