WebAVL Tree is invented by GM Adelson - Velsky and EM Landis in 1962. The tree is named AVL in honour of its inventors. AVL Tree can be defined as height balanced binary search tree in which each node is associated with a balance factor which is calculated by subtracting the height of its right sub-tree from that of its left sub-tree. WebAVL trees work by ensuring that the tree is height balanced after an operation. If we were to have to calculate the height of a tree from any node, we would have to traverse its two subtrees making this impractical. Instead, we store the height balance (or height) information of every subtree in its node. WebStep 1: First we create a Binary search tree as shown below: Step 2: In the above figure, we can observe that the tree is unbalanced because the balance factor of node 10 is -2. In order to make it an AVL tree, we need to perform some rotations. It is a right unbalanced tree, so we will perform left rotation. shanghai sinobizlink technology co. ltd
