When a tree becomes unbalanced due to a node being inserted as the left subtree of a left subtree the AVL tree will perform a right rotation. This leads to three changes in the subtree’s structure. The unbalanced node (node(C)) will become the right child of node(C)’s current left child.

WebOverview. AVL (Adelson-Velsky and Landis) Tree is a self-balancing binary search tree that can perform certain operations in logarithmic time. It exhibits height-balancing property by associating each node of the tree with a balance factor and making sure that it stays between -1 and 1 by performing certain tree rotations. This property prevents the Binary …
