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: [[3, 18, 0, -30], [39, -17], [14, -13], [-37, 37], [23, 31, -22], [25, -10], [30, 40, -43, -43, 13], [30, -46], [7, 1, -33], [-50, -26, 12]]

SOLUTION: [0, 0, 14, 0, -22, -10, 1200, -1380, 0, 15600]

PROBLEM: [[-46, -27], [47, -29, 30, -50], [-28, -47, -20, 28], [45, 10, 32, -11, -42], [26, -10, 17], [-31, -29, -30, 11, -49], [36, 10, -12, -34, 30], [-10, 30, -18, 23], [-36, 50, -14, 0], [-8, -44, 40, -45], [41, -16, 30], [38, 38, -46, 18, 31], [29, 43, 5, -42], [48, -28]]

SOLUTION: [-46, -1500, 15680, -13440, -260, -30, 4406400, 5400, 0, 14080, -480, -1195632, -42, -1344]
