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: [[-21, 48], [9, 37], [46, -29], [-32, -7, 45, -43, -32], [-35, 14, -42], [-45, 16], [-2, 24, 30, -42, 31], [9, -11, 10]]

SOLUTION: [48, 0, 46, 1024, -588, 16, 60480, 10]
