How to rebalance AVL tree after leaf deletion? - Stack Overflow

WebbThe AVL tree (named after its two inventors Adelson-Velsky and Landis) is a self-balancing binary tree. As you have seen many times by now, trees are very useful data structures but only if their height is closer to the optimal O (log n) than the worst case O (n). WebbEfficient rebalancing is the key to making the AVL Tree work well without sacrificing performance. In order to bring an AVL Tree back into balance we will perform one or more rotations on the tree. To understand what a rotation is let us look at a very simple example.
