FAQs

Question: What is the main advantage of using AVL Trees over Red-Black Trees?
Answer: AVL Trees provide faster lookups due to stricter balancing, while Red-Black Trees offer faster insertions and deletions.

Question: How do you determine the height of an AVL Tree?
Answer: The height of an AVL Tree can be determined by counting the number of edges from the root to the deepest leaf node.
