Given a Binary Search Tree. The task is to find the minimum element in this given BST.
Example 1:
Input:
5
/ \
4 6
/ \
3 7
/
1
Output: 1
Example 2:
Input:
9
\
10
\
11
Output: 9
Your Task:
The task is to complete the function minValue() which takes root as the argument and returns the minimum element of BST. If the tree is empty, there is no minimum elemnt, so retutn -1 in that case.
Expected Time Complexity: O(Height of the BST) Expected Auxiliary Space: O(Height of the 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.
