How do tree rotations work?

Can you explain how tree rotations work in binary search trees?

Sure! Tree rotations are operations that change the structure of a binary search tree while maintaining its properties.

What are the different types of tree rotations?

There are two main types: left rotation and right rotation. Each serves to balance the tree.

When would I need to use a tree rotation?

You would use tree rotations when the tree becomes unbalanced, typically after insertions or deletions.

Can you give me an example of a left rotation?

Absolutely! In a left rotation, the right child of a node becomes the new root of that subtree, and the original root becomes the left child of the new root.
