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: [[-42, -2, -12, -38], [17, -3], [3, -37, -38, -18], [49, 39, -43, 28, -35], [-9, -50, 49, 39], [-49, -16, -47], [-4, 30, 45, -12], [41, 36, -19, 18, -34], [-5, 48, -15, 49], [-24, -30, -16], [10, -16], [23, 34], [37, -45], [-29, -29, -26], [11, 41, 30, 33]]
