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: [[-5, 22], [-37, 18], [2, -32, -20, 10], [40, 45, -14, 5], [27, -5, -36, 22, -1], [2, -27, -38, 41], [-41, -16, -12, 18, 11], [17, -45, 23, -49]]

SOLUTION: [22, 18, 12800, -560, -792, -76, 3456, 0]

PROBLEM: [[-39, -5, -8], [-46, -42], [17, 14, -32, 37], [45, 42], [1, -25], [-33, 48, -33, -48]]

SOLUTION: [-8, 1932, -448, 42, 0, -2304]

PROBLEM: [[12, -24, -47, 40, 35], [-9, 31], [36, 10, 26, 13, 45], [-23, -34, -45, -24, 37], [15, 27, 39, 26], [-19, 45], [47, 44, -28, 4, 19], [-48, 7, 9, -12, -8], [9, 7], [40, -42, 37, -34], [-41, -48, -12, 37], [-20, -30, -26, 40]]

SOLUTION:
[-11520, 0, 9360, 816, 26, 0, -4928, -4608, 0, 57120, 576, -624000]
