What are the differences between BST and AVL trees?

What are the differences between BST and AVL trees?

BST (Binary Search Tree) allows for faster insertions and deletions, while AVL trees are self-balancing, ensuring O(log n) height.

Can you explain what self-balancing means in AVL trees?

Self-balancing means that AVL trees automatically adjust their structure after insertions or deletions to maintain a balanced height.

What are the advantages of using AVL trees over BST?

AVL trees provide faster search times in scenarios with frequent insertions and deletions due to their balanced nature.

Are there any disadvantages to using AVL trees?

Yes, AVL trees require more rotations during insertions and deletions, which can make them slower for these operations compared to BSTs.
