AVL tree may become unbalanced if a node is inserted in the left subtree of the left subtree. The tree then needs a right rotation. As depicted, the unbalanced node becomes the right child of its left child by performing a right rotation. This is also called an RR rotation. Let us see how it looks in code − WebI'm studying AVL Trees in my programming class and we got this exercise dealing with right, left, left-right and right-left rotations as a way to check if we understand the theoretical concept of AVL Trees.

How does the AVL tree achieve balance? Specifically, it is achieved by left-handed or right-handed. The ...

WebGenerally you'll want to rotate after any insertion or deletion that causes a tree to get "too tall" — AVL trees and Red-Black trees do this. Another approach is to constantly rotate after every insertion, deletion, and lookup to so as to bubble the most likely to be looked up elements near the top. Splay trees do this.
