Given a Binary Search Tree of size N, your task is to complete the function findMedian(), that return the median of Binary Search Tree.
Median of the BST are:
Given BST(with odd no. of nodes) is : 6 / \ 3 8 / \ / \ 1 4 7 9 Inorder of Given BST will be : 1, 3, 4, 6, 7, 8, 9 So, here median will 6. Given BST(with even no. of nodes) is : 6 / \ 3 8 / \ / 1 4 7 Inorder of Given BST will be : 1, 3, 4, 6, 7, 8 So, here median will (4+6)/2 = 5.
The function takes a single argument as input, the reference pointer to the root of the BST.
There will be T test cases and for each test case function will be called separately.
For each test case the function should return the Median of the BST.
