IBMCiscoGoogle inc

You have been given a Binary Search Tree (BST) of integer values and 2 integers 'LOW' and 'HIGH' denoting range ['LOW', 'HIGH'].

Your task is to return the count of nodes where all the nodes under that node (or subtree rooted with that node) lie in the given range.

A binary search tree (BST) is a binary tree data structure with the following properties.

• The left subtree of a node contains only nodes with data less than the node’s data.

• The right subtree of a node contains only nodes with data greater than the node’s data.

• Both the left and right subtrees must also be binary search trees.
Example:
Consider the following binary search tree. Suppose the given range is [ 15, 32 ] so we return ‘2’ as an answer as there are two nodes whose subtree is in the given range, the nodes are 20 and 30.
