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: [[45, -24, 39, -5, 39], [13, 1, 17, 19], [-10, 7, -30, 49, 19], [20, 5, -46], [8, 11, -1, -45, -50], [-14, -42], [21, 33, 3, -34], [-2, 7, -46, 15], [41, -19, 40]]
