what is an avl tree mcq

The technique of balancing the height of binary trees was developed by Adelson, Velskii, and Landi and hence given the short form as AVL tree or Balanced Binary Tree. (Formal definitions on request.) b) AVL tree store balance factor in every node which costs space The number of edges from the root to the node is called _____ of the tree. Every node in an AVL tree need to store the balance factor (-1, 0, 1) hence space costs to O(n), n being number of nodes. That means, an AVL tree is a binary search tree but i t is a balanced tree. AVL tree. IndianStudyHub is providing all AVL Tree | Data Structure MCQs pdf free download questions and answers along with detailed explanation and Answers in an easy and understandable way. AVL tree checks the height of the left and the right sub-trees and assures that the difference is not more than 1.

AVL Tree | Data Structure MCQs What is an AVL tree? a) log(n) where n is the number of nodes An AVL tree is a binary tree that has additional properties. A node must be either Red or Black in color and root node must be black. 1. The sub-trees of every node differ in height by at most one. Named after their inventors, Adelson-Velskii and Landis, they were the first dynamically balanced trees to be proposed.Like red-black trees, they are not perfectly balanced, but pairs of sub-trees differ in height by at most 1, maintaining an O(logn) search time. An AVL Tree (Adelson-Velsky and Landis tree) is a self balancing binary search tree such that for every internal node of the tree the heights of the children of node can differ by at most 1.
