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: [[16, 48, -44, -49], [44, -25, -39], [-8, -39, 30, 4], [15, -14, 1, -50, -11], [-20, -33, 10], [-29, -32, 48, 32, -29], [49, -35, 6, -39, -45], [9, -19]]

SOLUTION: [-33792, 44, -960, 700, -200, -49152, 6, 0]

PROBLEM: [[0, 50, 16, -48, 7], [-2, -21, 12, 44], [20, -45, 14, 47], [-48, 10, -17, 34, 21]]

SOLUTION: [0, -1056, 280, -16320]

PROBLEM: [[34, -23, 12], [45, -23, 29, -18], [2, 27, -26], [0, -30, -29], [-42, 24], [-41, -13, 16, 33, -41], [19, 30, -32, -17, 37], [-34, 25, -25]]

SOLUTION:
[408, -18, -52, 0, -1008, 16, -960, -34]
