What is an AVL tree?

An AVL tree is a type of binary search tree that is always in a state of partially balanced. The balance is measured as a difference between the heights of the subtrees from the root. This self-balancing tree was known to be the first data structure to be designed as such.

AVL Tree is Named after its inventor Adelson, Velski & Landis, are height balancing binary search tree.
