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: [[-21, -32, 1], [19, 31, -9, 40, 24], [49, -12, -36], [1, -17, -4, -47, 30], [-29, -38, -36]]

SOLUTION: [-32, 960, 432, -120, 1368]

PROBLEM: [[8, 27], [47, -6, -15, 5, 47], [-16, -48, 0, 37, -44], [-21, -20, 13, -47], [-38, -47], [-33, -19, 44, 24, 9], [47, -15], [-20, 5, -13, -18], [32, -27, 21, -34, 3], [-49, 38, 25]]

SOLUTION: [8, -6, 0, -20, -38, 1056, 0, 360, -1088, 38]

PROBLEM: [[-21, -5, -21, 30], [41, -9, 7, -37], [-33, -32, -3], [-17, -26, -33, 16, -3], [24, -35, -50, 41]]

SOLUTION:
[30, 0, -32, -416, -1200]
