Instructions: 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.
Input: [[3, -40, -34, -24, -24], [-24, 21, 9, -35], [48, 20, 25, -35, -32], [-36, 22, 37, -47, -9], [19, 26, -27, -41, 37], [7, -10], [5, 50], [-45, -49], [-42, 49, -3], [-45, -26], [36, -32, 3], [2, 6, 17, 27, 17]]
Output:
[783360, -24, -30720, -792, 26, -10, 50, 0, -42, -26, -1152, 12]
