Your Task:
The task is to complete the function buildBalancedTree() which takes root as the input argument, and returns the root of tree after converting the given BST into a balanced BST that has minimum possible height. The driver code will print the height of the updated tree in output itself.
Expected Time Complexity: O(N) Expected Auxiliary Space: O(N)
Here N denotes total number of nodes in given BST.

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
