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: [[-10, -18, 4, -33], [-9, 11], [40, -34, -40], [46, 2], [7, 38], [2, -24, 14], [9, 40], [-20, 21, 46, -23], [8, 50, 36], [45, -25, 8, -9, 48], [-46, 20, -9, -32, 4], [-35, -31, 28, 29], [-26, 12, 9]]

SOLUTION: [720, 0, 54400, 92, 38, -672, 40, -920, 14400, 384, 117760, 28, -312]
