WebIf balance factor of any node is -1, it means that the left sub-tree is one level lower than the right sub-tree. An AVL tree is given in the following figure. We can see that, balance factor associated with each node is in between -1 and +1. therefore, it is an example of AVL tree. ... LR Rotation. Double rotations are bit tougher than single ... WebOct 31, 2024 · The terminology for AVL trees consists of simple rotations (from left to right or vice versa) and double rotations (combinations of two simple rotations). When after a deletion of a node you move upwards in the tree, and find a balance-violation, this means that the temporarily updated balance factor in that node is either -2 or 2.
