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: [[16, -24, 20], [-28, 2], [-43, 21, -15, 9], [29, -48], [41, -1, 3, 38, 10], [12, -3, 35, -15, 24], [-15, 41, 42, -10, 44], [24, 40, -32, 24], [14, 11, 25, 36, -26], [30, 32], [-18, 43, 13]]
