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: [[-16, -31, -5, 28], [-1, -26], [-19, -9], [36, -3], [-43, -44, 20, -12], [-15, 11, 46, -20, -18], [33, -25], [-39, -12, 30, 37], [17, 10, 1, 28], [-37, 44, 34], [-14, -48, -35], [-23, 40, -22, -7, 6], [-44, 34, 31], [39, -27, 12, -40], [-25, -15, -39, 36]]
