FAQs

Question: What is the main difference between AVL trees and Red-Black trees?
Answer: AVL trees maintain a stricter balance than Red-Black trees, which allows for faster lookups but may require more rotations during insertions and deletions.

Question: How do rotations work in AVL trees?
Answer: Rotations are operations that help restore balance in AVL trees by rearranging the nodes after insertions or deletions, ensuring that the height difference between the left and right subtrees remains within one.
