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: [[-8, -44, -13, 2, 22], [17, 38], [43, -11, 17, -32, 45], [-6, 39, 32, 36, -45], [29, 24, 4, 21], [-33, -44, -43], [-44, 34], [8, 47, 5, 27, 10], [41, 45, 12, -7]]
