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: [[-27, 11, -13, 21, -36], [-11, -15, -17, -24, 16], [12, 15, -3, 21, -4], [-28, -2, -38]]

SOLUTION: [-36, -384, -48, -2128]

PROBLEM: [[-49, 5, -1, 42, -33], [20, -47], [2, -19, 16], [39, 20], [11, 3], [-9, 16, 23, 33], [33, 12]]

SOLUTION: [42, 20, 32, 20, 0, 16, 12]

PROBLEM: [[11, -30, 0], [-12, 32, 4, 31, 44], [-6, -26, 12], [35, 14, 11, -46], [-11, -6, -30, -27, 38], [9, 23, 24, -36, -50]]

SOLUTION:
[0, -67584, 1872, -644, 6840, 43200]
