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: [[8, 16], [-24, -11, -1, 35], [-12, 35], [-6, -27], [-38, 21, -21, 16], [43, 3], [-10, -37], [-34, 23, -12, -16], [-36, -12]]

SOLUTION: [128, -24, -12, -6, -608, 0, -10, -6528, 432]

PROBLEM: [[4, 48, 11, -29, -42], [2, -23, -18], [-7, -27], [-43, -18, -34, 16]]

SOLUTION: [-8064, -36, 0, 9792]

PROBLEM: [[-9, -26], [41, -9, -40], [45, 39, -38, -45], [-29, -4, 9, 30], [2, 32], [29, 25], [-24, -38, 21, 7, -26], [12, 50, -15], [-48, -29], [-10, -6, 43, -7, -31], [-30, -33, -17, 40], [47, 13, -32, 6]]

SOLUTION:
[-26, -40, -38, -120, 64, 0, -23712, 600, -48, 60, -1200, -192]
