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: [[-50, 11, 44], [50, 36], [-20, -48, -10, 23], [15, -11, 9, -2, -1], [37, -28], [-46, 44, -41], [20, 25], [7, 41, 2, -17, 18], [9, -29, 4], [-45, -15, -50, -5, -42], [-15, -21, -50, 35], [10, 44, -48, 16], [32, 28, -7, -30]]
