Given a set of elements, print the number of nonempty subsets where the maximum element is less than or equal to .
Two subsets are considered different if an element at index for some exists in the first subset but not in the second subset, or vice versa.
The first line will contain two integers , the number of elements.
The second line will contain integers, .
