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

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

PROBLEM: [[-29, -13], [22, -31, 40, 27], [-44, -16, 47], [-7, 10, 13], [14, -46], [-3, 14], [-22, -26, 29, 16], [-10, -31], [-43, 40, 4], [38, 19, -43], [50, 9, 2], [-33, -7, -35, -34], [43, 22, -46]]

SOLUTION: [0, 880, 704, 10, -644, 14, 9152, -10, 160, 38, 100, -34, -1012]

PROBLEM: [[-37, -42], [-14, 9, 30, -31], [-36, 7, -19, 22], [28, 3, -34, -40], [-9, 7]]

SOLUTION:
[-42, -420, -792, 38080, 0]
