Instructions: In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.
Input: [[37, -17, 50, -38, 5], [5, 3, 19, -47], [-25, 44], [38, -32, 50], [-20, -24]]
Output:
[-1900, 0, 44, -60800, 480]
