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: [[-12, 28, 9], [17, 50, 29], [7, 40, 27], [-22, 19, -11, -7, 2], [2, -6, -34], [-10, -35, -41, -3], [-50, 14, -14, -28], [-33, 9, 50, -2, 3], [6, 20, -40, -24, -30], [15, -5, -46, 13, 23], [39, 29], [48, 49, -23, -44]]
