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: [[-45, 37, 30], [-39, 24, -6, 26, -23], [18, -17, -15, 38], [-2, 25, 37], [24, 14, 13], [14, -15, 9, 46, 33], [-50, -47, 35, 19], [-8, -25, -14, -32, 12], [22, 22, 50, -21, 34], [48, -22], [41, 41], [33, 48, -20, 15, 13]]
