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:
[[31, 43, 9, 3], [-27, 50, 18, -46], [15, -43], [25, 36, -48, -12, -23], [-14, -35, -41, -23, -30], [-12, -38], [38, -20], [-25, 5, 29], [25, 31, 45, -50], [35, 17]]

Ex Output:
[0, -41400, 0, 20736, 420, 456, -760, 0, -50, 0]


Ex Input:
[[24, -1, -21, 4, -37], [-26, -29, -25], [-28, -18, -41], [26, -9], [44, -11, 5, 9]]

Ex Output:
[96, -26, 504, 26, 44]


Ex Input:
[[34, 23, 31, -44], [17, -3, -13], [28, -18, 20, -47]]

Ex Output:

[-1496, 0, -10080]
