/**

You have to implement the minStack class which will have a min() function.
3+
Whenever min() is called, the minimum value of the stack is returned in O(1) time.
4+
The element is not popped from the stack, its value is simply returned.
5+
6+
Keep in mind that the min function should work in O(1) and should not pop
7+
the minimum element out of the stack. It simply returns its value.
