Which specific tree data structure maintains balance by ensuring that for any node, the height difference between its left and right subtrees is at most one?

The specific tree data structure that maintains balance by ensuring that for any node, the height difference between its left and right subtrees is at most one is an AVL tree. An AVL tree is a self-balancing binary search tree, which means it automatically adjusts its structure to maintain balance after modifications. It was the first self-balancing binary search tree, named after its inventors, Adelson-Velsky and Landis. A node is a fundamental unit in the tree containing data and references to its child nodes. A subtree is a portion of a tree that can itself be considered a tree. The height of a subtree is defined as the number of edges on the longest path from its root down to a leaf no....
