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: [[-31, -27, -17, 46, -31], [17, 25, -2, 49, -31], [4, -38], [-48, -35, 18, -32], [13, 39, 25, 30], [38, 29, -3, 43, -26], [23, -21, -16, 24, 33]]

SOLUTION: [46, -2, -152, 27648, 30, -988, -384]

PROBLEM: [[-30, -18], [-46, -29, 34, -14, 22], [-16, -37, -47, -19], [-46, -42, -37, 34, -40], [7, -4, 22], [-17, -10, 8, -46], [44, 4, -39, -48], [-33, 39, 1, -28], [-3, 15, -14]]

SOLUTION:
[540, 481712, -16, -2627520, -88, 3680, -8448, -28, -14]
