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.

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.
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 is purpose of AVL tree?
AVL TreesIn computer science, an AVL tree is the first-invented self-balancing binary search tree. In an AVL tree the heights of the two child subtrees of any node differ by at most one, therefore it is also known as height-balanced. Lookup, insertion, and deletion are all O(log n) in both the average and worst cases. Additions and deletions may require the tree to be rebalanced by one or more tree rotations. The AVL tree is named after its two inventors, G.M. Adelson-Velsky and E.M. Landis, who published it in their 1962 paper "An algorithm for the organization of information."The balance factor of a node is the height of its right subtree minus the height of its left subtree. A node with balance factor 1, 0, or -1 is considered balanced. A node with any other balance factor is considered unbalanced and requires rebalancing the tree. The balance factor is either stored directly at each node or computed from the heights of the subtrees.
Which is better - AVL or Red Black Trees?
It depends on what the tree is being used for. If the tree is being used to store data that is not going to be modified very much, than AVL trees are probably better. In most other cases, I'd say Red-Black trees are better.
What is the complexity of AVL tree?
complexity of avl tree is o(n).
Who is the founder of AVL tree?
The AVL tree is named after its two inventors, G.M. Adelson-Velsky and E.M. Landis.

Advantages of AVL TREE?
not much memory wastage.
What is the full form of avl tree?

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.
