FAQs

Question: What is the main difference between AVL 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 I implement an AVL tree in C++?
Answer: You can implement an AVL tree by defining a node structure, then creating functions for insertion, deletion, and balancing the tree using rotations.
