Explain the rotation operations used in AVL trees and their significance in maintaining balance.
- Primary and secondary rotations; Primary rotations adjust immediate subtrees, while secondary rotations modify distant subtrees.
- Simple and complex rotations; Simple rotations involve basic adjustments, while complex rotations involve intricate reconfigurations.
- Single and double rotations; Single rotations involve left or right rotations, while double rotations involve combinations of single rotations.
- Triple and quadruple rotations; Triple rotations involve three consecutive rotations, while quadruple rotations involve four rotations simultaneously.
Rotation operations used in AVL trees are single and double rotations. Single rotations include left rotations and right rotations, which help maintain balance by adjusting the heights of subtrees. Double rotations are combinations of single rotations performed to restore balance in specific cases, such as the double rotation involving left-right or right-left rotations.
