WebAug 3, 2024 · If a binary search tree has a balance factor of one then it is an AVL ( Adelso-Velskii and Landis) tree. This means that in an AVL tree the difference between left subtree and right subtree height is at most one. AVL tree is a self-balancing binary search tree. In an AVL tree if the difference between left and right subtrees is greater than 1 ... WebAfter deletion, retrace the path back up the tree (parent of the replacement) to the root, adjusting the balance factors as needed." That should be enough to answer why 28 is used to replaced the node 22 -- the smallest value of the right sub tree. It doesn't matter whether or not a node is the root.
Binary Search Trees vs. AVL Trees: the Complexity of Construction
WebThe AVL tree (named after its two inventors Adelson-Velsky and Landis) is a self-balancing binary tree. As you have seen many times by now, trees are very useful data structures but only if their height is closer to the optimal O (log n) than the worst case O (n). Accordingly, by balancing a tree when necessary, we can achieve a guaranteed O ...
