Learn how to perform deletions in AVL trees through a detailed 27-minute tutorial. Explore the process of deleting existing nodes and rebalancing the tree when the balance factor becomes imbalanced. Follow along with step-by-step diagrams and explanations as the instructor solves a practical example, demonstrating the necessary rotations to maintain the AVL tree's self-balancing property. Gain a deeper understanding of AVL tree operations and their importance in maintaining efficient data structures for search, insertion, and deletion operations.
