WebDefinition Balance factor. In a binary tree the balance factor of a node X is defined to be the height difference ():= (()) (()): 459 of its two child sub-trees. A binary tree is defined to be an AVL tree if the invariant {,,}holds for every node X in the tree. A node X with () < is called "left-heavy", one with () > is called "right-heavy", and one with () = is sometimes simply called …

WebAn AVL tree is a balanced binary search tree where every node in the tree satisfies the following invariant: the height difference between its left and right children is at most 1. Hence, all sub-trees of an AVL tree are themselves AVL. The height difference between children is referred to as the balance factor of the node. WebSep 14, 2024 · The name AVL tree is derived after its two creators, i.e. G.M. Abelson-Velvety and E.M. Landis. AVL tree is a height-balanced binary tree where a balance factor balances each node.
