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: [[6, 20, -46], [-46, -30], [-20, 23, -21], [28, -8, -33, -34], [17, -18], [-23, 12], [-44, -45, 6, -44, 11], [-45, 35, -18], [31, 34, -10], [-27, 0, -2], [-26, -9, -39, -38, 12]]
Output:
[-5520, 1380, -20, 7616, -18, 12, 11616, -18, -340, 0, 11856]
