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, 30, -21], [-47, 7], [1, -15, -22, -37, 27], [35, -17, -33], [-44, -1], [-10, -27, 44, 5], [36, 12], [27, 40], [-27, -1, 10, -44, -1], [-4, 45, 34, -46, 14], [-27, -20, -2, -3, 24], [-45, -12, -30, 28, 42], [-8, 33, -5, -32], [-17, -22, 4]]
