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.
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.

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.
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.
Which data structure, AVL tree or Binary Search Tree, is more efficient in terms of balancing and searching for elements?
An AVL tree is more efficient than a Binary Search Tree in terms of balancing and searching for elements. AVL trees are self-balancing, ensuring that the tree remains balanced after each operation, which results in faster search times compared to Binary Search Trees.
Who is the founder of AVL tree?
The AVL tree is named after its two inventors, G.M. Adelson-Velsky and E.M. Landis.

What are the key differences between a binary search tree and an AVL tree in terms of their structure and performance?
A binary search tree is a data structure where each node has at most two children, and the left child is less than the parent while the right child is greater. An AVL tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one. The key difference between a binary search tree and an AVL tree is that AVL trees are balanced, meaning that the heights of the subtrees are kept in check to ensure faster search times. This balancing comes at the cost of additional overhead in terms of memory and time complexity for insertion and deletion operations. Overall, AVL trees provide faster search times compared to binary search trees, but with increased complexity in terms of maintenance.
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.
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

What are the key differences between an AVL tree and a binary search tree, and how do these differences impact their performance and efficiency in terms of search operations?
An AVL tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one. This ensures that the tree remains balanced, leading to faster search operations. In contrast, a binary search tree does not have this balancing property, which can result in an unbalanced tree and slower search times. Overall, AVL trees are more efficient for search operations due to their balanced nature, while binary search trees may require additional operations to maintain balance and optimize performance.
What is the worst-case height of an AVL tree?
The worst-case height of an AVL tree is approximately 1.44 times the logarithm of the number of nodes in the tree.
How can one ensure the efficient balancing of a binary search tree?
To ensure efficient balancing of a binary search tree, one can use self-balancing algorithms like AVL trees or Red-Black trees. These algorithms automatically adjust the tree structure during insertions and deletions to maintain balance, which helps in achieving optimal search and insertion times.
Is an AVL tree a binary search tree (BST)?
Yes, an AVL tree is a type of binary search tree (BST) that is balanced to ensure efficient searching and insertion operations.
