Given a binary search tree and an integer ‘K’. Your task is to find the ‘K-th’ smallest element in the given BST( binary search tree).

BST ( binary search tree) -

If all the smallest nodes on the left side and all the greater nodes on the right side of the node current node.

Example -

Order of elements in increasing order in the given BST is - { 2, 3, 4, 5, 6, 7, 8, 10 }

Suppose given ‘K = 3’ then 3rd smallest element is ‘4’.

Suppose given ‘K = 8’ then 8th smallest element is ‘10’.

Note:

1. You are not required to print the output explicitly, it has already been taken care of. Just implement the function and return the ‘K-th’ smallest element of BST.
2. You don’t need to return ‘K-th’ smallest node, return just value of that node. 
3. If ‘K-th’ smallest element is not present in BST then return -1.
