When the balance factor of a node reaches -2 or 2, a rotation is needed to restore the balance factor. Keeping track of balance factor instead of height/depth means that only the nodes involved in a rotation … WebIn 1962, Adelson Velski & Lendis, the two creators of AVL tree published the concept of AVL tree in the paper “An algorithm for the organization of information”.

WebAVL trees work by ensuring that the tree is height balanced after an operation.

How avl tree works

WebAfter insertion you simply climb up the tree and update balance factors: retrace the tree if the balance factor becomes -2 or 2 (this can be achieved by local rotations on the tree), if balance factor becomes 0, then the tree became balanced and no further work is required. For more details check wikipedia page. 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.
