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 can I implement an AVL tree in Python?
Answer: You can implement an AVL tree in Python by defining a class for the tree nodes and including methods for insertion, deletion, and balancing the tree.
