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 insertion and deletion operations.

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