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. WebGiven the root node of a binary search tree and two integers low and high, return the sum of values of all nodes with a value in the inclusive range [low, high]. Example 1: Input: root = [10,5,15,3,7,null,18], low = 7, high = 15 Output: 32 Explanation: Nodes 7, 10, and 15 are in the range [7, 15]. 7 + 10 + 15 = 32. Example 2:
