How can I balance a binary search tree?

To balance a binary search tree (BST), you can use techniques like AVL trees or Red-Black trees. Would you like to know more about one of these methods?

Yes, tell me about AVL trees.

AVL trees maintain balance by ensuring that the heights of the two child subtrees of any node differ by at most one. This is done through rotations during insertions and deletions.

What are the advantages of using AVL trees over regular BSTs?

AVL trees provide faster lookups compared to regular BSTs because they are more balanced, which reduces the height of the tree.

Can you show me an example of balancing a BST?

Sure! If you have an unbalanced BST, you can perform rotations to balance it. For example, a right rotation can help balance a left-heavy tree.
