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, 6], [17, -46], [-2, 9], [-16, 15], [-38, -25], [-14, -12, 33, -6]]

SOLUTION: [48, -46, -2, -16, -38, -1008]

PROBLEM: [[-8, -47, 38, 16], [-8, 10, -29, 34], [-9, 29], [17, -30, 31, 11], [28, 16, 33, -29], [-28, -35, -47, 14], [50, 34, -15], [-36, 23, 1, -31, -29], [41, 46, 1], [-29, -16, 10, 12, 43], [-25, -22], [4, 49], [-23, -7, 27], [50, 35], [-19, -30, 8, 15]]

SOLUTION: [-4864, -2720, 0, -30, 448, -392, 1700, -36, 46, -1920, -22, 4, 0, 50, -240]

PROBLEM: [[12, -28, 0, 6], [17, 47], [35, 20, 16, 36, -9], [7, 46, -37]]

SOLUTION:
[0, 0, 11520, 46]
