Binary Search trees offer improved average case performance for searching. However, if they are unbalanced their search performance degrades to that of a linked list. AVL trees guarantee that the difference in height of any two subtrees rooted at the same node will be at most one. This guarantees an asymptotic running time of O(log(n)) as opposed to O(n) in the case of a standard bst.

What is the complexity of AVL tree?
The time complexity of operations in an AVL tree is O(log n), where n is the number of nodes in the tree. This is because AVL trees are balanced, ensuring that the height of the tree remains logarithmic with respect to the number of nodes.
Who is the founder of AVL tree?
Georgy Adelson-Velsky and Evgenii Landis are credited as the founders of the AVL tree data structure, which is a self-balancing binary search tree.

What is height of AVL tree?
o(logN)
IS AVL-Tree IS binary tree?
An AVL tree is another balanced binary search tree. 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. Addition and deletion operations also take O(logn) time.Definition of an AVL treeAn AVL tree is a binary search tree which has the following properties: The sub-trees of every node differ in height by at most one.Every sub-tree is an AVL tree.
Advantages of AVL TREE?
not much memory wastage.
What is the full form of avl tree?
Adelson-Velskii and Landis (balanced binary tree)
In an AVL tree at what condition the balancing is to be done?
In an AVL tree, at what condition the balancing is to be done : If the 'pivotal value' (or the 'Height factor') is greater than 1 or less than -1. niraj
What are the applications of avl tree?
Binary Search Tree and AVL Tree are dictionary data structures. They are used for many search operations and also those operations where data is constantly inserted and deleted. AVL trees provide a better efficiency than BST as they maintain their upper bound of O(n*log n) through rotations.Eg: the map and set library in c++ isimplementedusing trees.
What do you mean by re balancing of AVL tree?
AVL tree definition a binary tree in which the maximum difference in the height of any node's right and left sub-trees is 1 (called the balance factor) balance factor = height(right) - height(left) AVL trees are usually not perfectly balanced however, the biggest difference in any two branch lengths will be no more than one level
How do you implement insertion into AVL tree in C plus plus?
See related links for an example.
Why AVL tree consider ideal?
No data container can ever be considered ideal in every case, including an AVL tree. Unordered containers that are ideal for quick insertion (which includes extraction) are not ideal for quick searching, while containers that are ideal for quick searching are not ideal for quick insertion. When we require both these operations, we must compromise one for the other. AVL trees are ideal for searching, but they are not ideal for insertion or extraction due to the need to re-balance the tree every time the tree changes.
