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: [[7, -10, -13, 43], [50, -1, 48, -29], [-36, 35], [-3, 34, 4, -45, 17], [-44, 34, 31]]

SOLUTION: [-10, 2400, -36, 136, -1496]

PROBLEM: [[28, 29, 14, -36], [-35, -16], [-39, -2, -25, -36], [-28, -5, 33, 18, 35], [20, -32, -14, 38], [40, -27], [-1, 20, -26, 4, 24], [-37, -23], [-2, -19], [-15, -39, 12, -33], [26, -34], [-42, -7, -27, 30], [44, -48]]

SOLUTION: [-14112, -16, 72, -504, 340480, 40, -49920, 0, -2, 12, -884, -1260, -2112]

PROBLEM: [[8, 39, 27], [-4, 36, -49, 0, -19], [-40, 38, 35], [-14, 16, 7, 13], [-45, -2, 50], [-28, 38, -35], [-38, -40, 43], [28, -49, -15], [39, -43, 12, 1, -40], [-10, 19, -19], [-6, 14, 31, 46, 24], [6, -33, 4, 41, 5], [-21, 24, 31, -34]]

SOLUTION:
[8, 0, -1520, -224, -100, -1064, 1520, 28, -480, -10, -92736, 24, -816]
