How do you delete a node from an AVL tree?

To delete a node from an AVL tree, you first perform a standard binary search tree deletion, then check for balance.

What happens if the tree becomes unbalanced after deletion?

If the tree becomes unbalanced, you'll need to perform rotations to restore the AVL property.

Can you give me an example of deleting a node?

Sure! Let's say we want to delete the node with value 30. After deletion, we check the balance and may need to rotate.

What types of rotations are used in AVL trees?

The main types of rotations are single right, single left, double right-left, and double left-right rotations.
