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: [[47, 10], [5, 3], [40, 0], [3, 30, -35], [-2, 3], [33, 7, 42, 12, 29], [-27, 17, -46, 10], [45, -9, -4, -28], [44, 38, 26]]

SOLUTION: [10, 0, 0, 30, -2, 504, -460, 112, 43472]

PROBLEM: [[-39, -14, 23, -37, 41], [-24, 49, -29, 38], [-49, -46, -8, -28, 0], [40, -29, 11, 20], [6, 13, -41, -34], [-26, -42, 2, -2], [-22, -11, 24, -35, -36]]

SOLUTION: [-14, -912, 0, 800, -204, -4368, 19008]

PROBLEM: [[-50, 2, 25], [-27, -18, 7], [-17, 6, 9, -35], [-34, 33, -48, 19], [-31, 9], [29, -29], [47, 5], [-1, 29, 26], [-23, -7], [26, -7, 40, 36]]

SOLUTION:
[-100, -18, 6, 1632, 0, 0, 0, 26, 0, 37440]
