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: [[-31, -27, -17, 46, -31], [17, 25, -2, 49, -31], [4, -38], [-48, -35, 18, -32], [13, 39, 25, 30], [38, 29, -3, 43, -26], [23, -21, -16, 24, 33]]

SOLUTION: [46, -2, -152, 27648, 30, -988, -384]

PROBLEM: [[-32, 1, 1, -48], [-36, -24, -4, -36, 11], [18, -45], [-7, 25, -29, -6], [-39, -36], [44, -44, 0, 1, -49], [9, 32, -33, -34], [26, -18, -38, 48, 1], [-16, 10, 49]]

SOLUTION: [1536, 124416, 18, -6, -36, 0, -1088, 853632, -160]

PROBLEM: [[-19, -24, 44, 15, -49], [44, 23, 22], [-46, -36, 7], [6, 30, -22, 35], [-19, 32, -18, 10, -16], [48, -8], [-10, 9, -24, 25, 21], [-23, -21], [-15, -2], [37, -31, -4], [36, -35], [19, -29, 16, 29], [-47, -38], [41, 49], [-11, -12]]

SOLUTION:
[-1056, 968, 1656, -3960, 92160, -384, 240, 0, -2, -4, 36, 16, -38, 0, -12]
