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: [[27, 24], [-42, 35, 28, -32, -18], [-33, 4, 1, 24, -20], [-47, 40, 33, 15], [-24, 31]]
