The task is to restore or fix the BST, without changing its structure. A binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree whose internal nodes each store a key greater than all the keys in the …
WebThus, BST divides all its sub-trees into two segments; the left sub-tree and the right sub-tree and can be defined as −. left_subtree (keys) < node (key) ≤ right_subtree (keys) Representation. BST is a collection of nodes arranged in a way where they maintain BST properties. Each node has a key and an associated value.
