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: [[38, 38, -20, 48], [6, -47, 38], [-22, -42, -50, -38, -19], [-40, -49], [-45, 3], [-27, 1], [-43, 11, 1]]
Output:
[-1386240, 228, 1755600, -40, 0, 0, 0]
