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: [[-14, 2, 24, -49], [-18, -8, 18, 50], [-40, 37, -41, 7], [-15, 37, 36], [-17, -5, -10, 43], [47, -2, 28], [2, 1, 32], [19, 31], [-31, -44, -31, -20, -21]]
