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, -1], [-22, -50], [31, -29, 49], [39, -26, -20, -44], [-46, 6, -30, 5, -24], [19, 49, -5], [-26, -1, 5], [47, 14, -16, 13, -32], [40, 8, 29, 5], [40, -43, -14, 37]]

SOLUTION: [18, 1100, 0, -22880, -198720, 0, -26, 7168, 320, -560]

PROBLEM: [[-40, -26, -39], [42, -4, 26, 9, 12], [-18, -8, 37], [-15, 33, -50, -5, -3], [-2, 39, -36], [24, -20, -35, -43], [13, 49, 37, 20], [29, 10, -10, -14], [5, 3], [-3, -20, -1]]

SOLUTION: [1040, -52416, 144, -50, 72, -480, 20, 1400, 0, -20]

PROBLEM: [[-11, 43, 1, -41], [11, 5, -4], [-6, -22, -50], [-11, 48], [37, -18, -10, 10, 39], [-20, 28, 37], [-46, 27], [-2, 18, -32, -15, 48], [-44, 29], [49, -37, 0], [30, 44, 17, 1, 17], [33, -3], [6, 10], [-26, 21, -13], [3, -22, 3, 25, 25]]

SOLUTION:
[0, -4, -6600, 48, 1800, -560, -46, 55296, -44, 0, 1320, 0, 60, -26, -22]
