In avl tree the balancing factor is checked

In AVL trees, after each operation like insertion and deletion, the balance factor of every node needs to be checked. If every node satisfies the balance factor condition, then the operation can be concluded. Otherwise, the tree needs to be rebalanced using rotation operations. There are four rotations and they are … See more An AVL tree is a type of binary search tree.

WebSimilar to the insertion in BSTs, the new node is inserted as a leaf node in AVL Trees. The balance factor of the new node inserted as a leaf node always equals 0. The insertion of this new node in the tree may change the balance factor of other nodes in the tree. We have to check if the tree is balanced or not. WebAVL tree checks the height of the left and the right sub-trees and assures that the difference is not more than 1. This difference is called the Balance Factor. Here we see that the first tree is balanced and the next two trees are not balanced −.
