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: [[29, 40, 15], [34, 17, 34, -26], [-9, -13, 42, 42], [13, -1, 3, -22, -14], [-35, 19, -17, -48]]

SOLUTION: [40, -30056, 1764, 308, -48]

PROBLEM: [[-40, 13], [46, -39, -23], [-43, 35, 0, -22], [-23, 21, 28, -1], [14, -29], [-9, 8, 29, 48], [28, 11, -1], [10, 6], [38, -13, -14, -15, 6], [-25, 25], [22, -27], [6, -34], [-41, 3], [10, 21, -2, 31], [-26, -39, 35]]

SOLUTION: [-40, 46, 0, 28, 14, 384, 28, 60, -3192, 0, 22, -204, 0, -20, -26]

PROBLEM: [[33, -16, -30, -6], [19, -1, -49, 27], [-15, -13, -39, 28]]

SOLUTION:
[-2880, 0, 28]
