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: [[1, 46, -20], [36, -9, 24, 43, -5], [-45, 7], [29, -3, -23, 47, 23], [-12, -6], [40, -32, 4], [-17, -30, 13, 9]]

SOLUTION: [-920, 864, 0, 0, 72, -5120, -30]

PROBLEM: [[-50, 1], [-35, 28], [-44, -28, -37, 45], [17, 29, -26], [21, 4]]

SOLUTION: [-50, 28, 1232, -26, 4]

PROBLEM: [[33, 47], [30, 36, -7], [-43, -41, 15, -3], [-42, -9], [-17, -39, 31], [-22, -4, -31, 7], [-43, -19], [20, -48, -17, 46, 41], [11, 26, -1, -22], [5, -37, -15, -47], [42, 8]]

SOLUTION:
[0, 1080, 0, -42, 0, 88, 0, -44160, -572, 0, 336]
