How do I balance a binary search tree?

To balance a binary search tree, 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 after insertions or deletions.

What are the types of rotations used in AVL trees?

There are four types of rotations: Left Rotation, Right Rotation, Left-Right Rotation, and Right-Left Rotation. Each is used to restore balance after an insertion or deletion.

Can you give me an example of how a rotation works?

Sure! For instance, in a Right Rotation, if a node becomes unbalanced due to a left child being added, the right rotation will make the left child the new root of that subtree.
