What is a Binary Tree and how to perform Inorder, Preorder, and Postorder Traversal in Java?
In this practical DSA tutorial, you’ll learn how binary trees work and how to traverse every node in different systematic ways using Java.

Welcome to The Techzeen, where I make Data Structures & Algorithms simple for beginners in Hindi/Urdu with real-world examples and interview-focused clarity

In this video, you’ll learn:
What is a Binary Tree and why it’s important in DSA
Node creation & linking (Left & Right child nodes)
Inorder Traversal (Left → Root → Right)
Preorder Traversal (Root → Left → Right)
Postorder Traversal (Left → Right → Root)
Step-by-step practical coding in Java
Time Complexity analysis for each traversal

This tutorial is perfect for:
Beginners learning Java & DSA
Students preparing for coding interviews
Anyone who wants to visualize and master Tree Traversals conceptually and practically
