DS Lab: Binary Trees in Java | Preorder, Inorder & Postorder Traversals

📄 Welcome to the Data Structures Lab – Binary Trees in Java! In this lecture, we explore the binary tree, a fundamental hierarchical data structure. You will learn how to implement binary trees, perform different types of traversals, and solve practical problems using recursion. ✔ Topics Covered in This Lecture 1. Binary Tree Basics - Tree structure and terminology (root, leaf, height, depth) - Node class structure and building a sample tree 2. Tree Traversals - Preorder Traversal (Root → Left → Right) - Inorder Traversal (Left → Root → Right) - Postorder Traversal (Left → Right → Root) 3. Example Demonstrations - Step-by-step implementation of all traversals - Visual diagrams of tree structure and traversal order - Full Java code with detailed comments 4. Activities for Students (to solve independently) - Calculate height of a binary tree - Level order traversal - Check if tree is height balanced - Build tree from preorder & inorder arrays - Find lowest common ancestor (LCA) 📌 GitHub – Full Code & Activities Repository link: https://github.com/Maryam-Skaik/java-ds-lab-trees Contains: - Binary tree examples (preorder, inorder, postorder) - Student activities (without solutions) - Lecture slides & diagrams 📘 This is Lecture 6 of the DS Lab series. Follow along in your IDE (NetBeans / VS Code / IntelliJ) and practice each example to strengthen your understanding. #Java #DataStructures #BinaryTree #TreeTraversal #Preorder #Inorder #Postorder #Recursion #DSLab #JavaProgramming #MaryamSkaik
