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: [[5, 41], [-23, 34, 43, -15], [-6, 31, 12], [29, 48, 7], [-16, 36, 28, -2, -5], [-46, 30], [11, -31, 30, -47, -18], [29, 23], [7, 2], [-40, -2, 35, -48], [48, -38, -30, 27], [-24, 39]]

SOLUTION: [0, 34, -72, 48, 32256, -1380, -540, 0, 2, -3840, 54720, -24]
