TASK DEFINITION: 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.
PROBLEM: [[-24, -39, 47], [-2, 26, 10, 25], [-34, -16, 40, -16], [47, -24, 46, -38, -10], [-6, -39, 19], [-44, -36, -14, 2]]
