AVL Tree in Data Structures and Algorithms Explained
The process of AVL tree balancing begins immediately after every insertion or deletion. The algorithm updates the height of all affected nodes and checks the balance factor while moving toward the root. If every node remains balanced, the operation ends normally. If an imbalance is detected, the appropriate Single Rotation or Double Rotation is performed according to the insertion pattern. This approach avoids rebuilding the entire tree and improves overall efficiency.
