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.

Ex Input:
[[46, 46], [1, -11], [-10, 6, -11], [-32, -37, -50, 31]]

Ex Output:
[2116, 0, -60, 1600]


Ex Input:
[[42, 47, -40], [-10, 47], [-23, 24]]

Ex Output:
[-1680, -10, 24]


Ex Input:
[[50, -26, 6], [-40, 6], [19, -40], [36, 32, -10, 22, 1], [-18, -14], [-44, 27], [19, -8], [-15, 33, 42, -24, -37], [43, 28, -19]]

Ex Output:

[-7800, -240, -40, -253440, 252, -44, -8, -1008, 28]
