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: [[-21, -32, 1], [19, 31, -9, 40, 24], [49, -12, -36], [1, -17, -4, -47, 30], [-29, -38, -36]]

SOLUTION: [-32, 960, 432, -120, 1368]

PROBLEM: [[-11, 19, 27, 12], [11, 23, 50, 46], [43, 2], [26, 21, -48, -42, -15], [38, 42, -2], [41, -27, -37, -18, -4], [37, 22], [-19, 32, 44], [-36, -16, 49, 40], [-26, -21, 6], [-40, 1, -42, 10, -26], [34, 30], [5, -27, -48, -35, -20], [46, 32, -9, -32]]

SOLUTION: [12, 2300, 2, 52416, -3192, 72, 22, 1408, 23040, -156, -436800, 1020, 960, -47104]

PROBLEM: [[-49, -24, -16], [-21, 34, 28], [-28, 19], [25, -30, -3, -37], [18, -47], [4, 45], [22, 20], [-17, 7, 40, 16, 32], [17, -28, 40, -37, 37], [-38, 22], [38, -13, -40, 43], [30, -10, -24, 50, 18], [22, -32], [15, 26, 27, -33, -4]]

SOLUTION:
[384, 952, -28, -30, 18, 4, 440, 20480, -1120, -836, -1520, 6480000, -704, -104]
