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: [[-29, -46, 2, -48], [-48, 38, -16, -34], [-26, 4], [22, 43, 0, -24], [28, -30, -23], [45, -38, 17], [-36, -3, 35], [14, -20, -6], [-27, -47, -25], [29, -21, 37, -46], [2, -1], [-38, -41, 21, 31], [-9, -4, 33]]
