AVL Tree & Heap Tree in DSA | Rotations, Heapify, Creation, Examples Explained | DSA | BCA

📚 AVL Tree & Heap Tree in Data Structures | DSA Theory Playlist | BCA

In this video from the DSA Theory Playlist, we cover two important advanced tree structures: AVL Tree and Heap Tree, both widely used in competitive programming, coding interviews, and real-world systems.

💡 What You’ll Learn in This Video:
🌳 AVL Tree (Adelson-Velsky and Landis Tree)
🔹 What is an AVL Tree?
🔹 How it extends Binary Search Tree (BST)
🔹 Importance of balance factor and how it’s calculated
🔹 When and why AVL trees are used in DSA
🔹 Understanding rotations for self-balancing: Right Rotation (RR), Left Rotation (LL), Left-Right Rotation (LR), Right-Left Rotation (RL)

🔹 Detailed diagrams and value-based examples for each rotation
🔹 Creation of an AVL Tree

🌀 Heap Tree in DSA
🔸 What is a Heap Tree?
🔸 How it relates to Complete Binary Tree
🔸 What is a Heap and its real-world applications
🔸 Types of Heaps: Max Heap, Min Heap
🔸 Differences between Max Heap & Min Heap (with diagrams)
🔸 Step-by-step process to: Insert a node, Apply heapify, Create a Max Heap from a given set of values
🔸 Visual explanation of swaps and heapify logic
