Asked in companies
You have been given a Binary Tree of 'N' nodes, where the nodes have integer values. Your task is to return the size of the largest subtree of the binary tree which is also a BST.
A binary search tree (BST) is a binary tree data structure which has 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:
Given binary tree:
