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: [[-48, 30, 27, -17], [22, 37, -29], [-17, 21, -50, 43], [20, -15, -25, 31, 5], [21, 50, -43], [-39, 13, 17], [34, 42, 6, -3], [-43, 45, 10], [33, -15, -32, -7], [-44, -12], [-42, -23], [12, -35, -48, -48], [-2, -26, 10, -48]]
