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: [[44, 11, -29, -18], [4, 9, 48], [-31, -30, -29, 34], [-26, 24, 22, 34], [22, 38, 1, 17, -50], [27, -46, -25], [-1, 15, -40]]

SOLUTION: [-792, 192, -1020, -466752, -41800, -46, -40]

PROBLEM: [[8, 16], [-24, -11, -1, 35], [-12, 35], [-6, -27], [-38, 21, -21, 16], [43, 3], [-10, -37], [-34, 23, -12, -16], [-36, -12]]

SOLUTION: [128, -24, -12, -6, -608, 0, -10, -6528, 432]

PROBLEM: [[34, -47, 35, 12], [-38, -22, -24, 41], [-12, -6, -48, 15, -12]]
