WebCan you solve this real interview question? Validate Binary Search Tree - Given the root of a binary tree, determine if it is a valid binary search tree (BST). A valid BST is defined as follows: * The left subtree of a node contains only nodes with keys less than the node's key. * The right subtree of a node contains only nodes with keys greater than the node's key. … WebA representation of binary search tree looks like the following: Consider the root node 20. All elements to the left of subtree (10, 5) are less than 20 and all elements to the right of subtree (25, 30, 35) are greater than 20. Implementation of BST First, define a struct as tree_node. It will store the data and pointers to left and right subtree.
