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: [[-19, 13, -50, 3], [9, -18], [5, -19, -36, 41], [34, 44], [34, -25, 13, 48, -24], [46, 14, -18], [34, 33, -8, 12], [-39, 18, 38], [8, -42, -45, -36, 9], [-43, 23, 38, 42], [-14, 14, 22], [46, -10, -39, -46], [-21, -25, 47, -47, -38], [-37, 0, 27], [-46, 3, -32]]
Output:
[-50, -18, -36, 1496, -39168, -11592, -3264, 684, 12096, 1596, -4312, 21160, -38, 0, 1472]
