Learn about the four essential rotations in AVL trees - LL, RR, LR, and RL - used to maintain balance during insertion and deletion operations. Explore the properties of AVL trees and understand how these rotations transform imbalanced nodes into balanced ones. Gain a comprehensive understanding of each rotation type, including their implementation and effects on tree structure. Master the techniques for maintaining the self-balancing property of AVL trees, a crucial aspect of this efficient data structure.
