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: [[-6, -27], [50, -8], [21, -43], [29, 45], [48, -25, -2], [22, 12, -49, -45, 20], [-9, 45], [-25, 17, -49, -43], [38, 12, -13, 49, -40], [40, -27], [1, 5, 18], [26, 47, -31, 21]]
