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: [[35, -38, 16, -3], [-26, -45, 45, -7], [20, -38, 40, -42, 33], [-34, 37], [31, 20], [-4, 6, 17], [-17, 16], [-21, -7, 11, 31]]

SOLUTION: [-608, -26, 1276800, -34, 20, -24, 16, 0]
