AVL Tree in One Shot || Part 2 || Data Structures and Algorithms

Welcome to Part 2 of the AVL Tree One Shot series, where we transition from the mechanics of insertion to the intricate logic of node deletion and mathematical analysis. In this session, we analyze the "ripple effect" of deletions, where removing a single node can trigger multiple imbalances up the tree. You'll learn how to identify these shifts and apply the correct rotations to maintain O(log n) efficiency. Key Topics Covered : Deletion Mechanics: Step-by-step logic for removing leaf nodes, nodes with one child, and nodes with two children. Advanced Rebalancing: How to handle the unique "double imbalance" scenarios often found during the deletion process. Mathematical Bounds: Understanding the relationship between tree height and the minimum/maximum number of nodes. 📌 Link to lecture notes : https://drive.google.com/file/d/1TUSeNi1c2upZ0xy9-Aa2kGcoxS-l8_ST/view?usp=sharing Link to Part 1 : https://youtu.be/3l8fRFBxW3k?si=-NQATmKSUBWp7EtP #avltrees #DataStructures #OneShot #ProgrammingTutorial #CodingInterview #GATE2026 #ComputerScience
