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: [[-18, -47, -47, -6, -8], [24, -17, 48, 24], [-47, -3, -6, -4], [6, -38], [35, -25, 14], [-41, 1], [-36, -31, 40, 18, 36], [-44, 13, -8], [-16, -13, 24, 32, 33], [3, 13], [40, 32]]
