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: [[-27, -1], [-28, -48, -29, 29, -27], [-40, 46, -46, 22, -34], [-30, 48, 14], [-16, -19], [27, 40], [-42, -48], [10, 31, -41, 47], [-19, 37, 31], [12, -46, -34, -40, 5], [-41, 0, 12, 46, 36], [-16, 7, -50, 26, -2], [20, -46, -38]]
