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:
[[-2, 41, -50, -30], [5, -47], [35, 6, -46, 21], [33, 23, -6, -26], [-46, -15, -2], [-16, 29], [-20, -12, -20, -50]]

Ex Output:
[-3000, 0, -276, 156, 92, -16, 240000]


Ex Input:
[[46, 14], [-42, 2, 18], [40, -33, 39, 16, -24], [-37, -43, -29, -18], [-27, -46], [-38, -26, 41]]

Ex Output:
[644, -1512, -15360, -18, -46, 988]


Ex Input:
[[-31, -7, -3, 11, 7], [22, -50, -49, -17, 39], [-36, -41, -21, -9], [28, -8], [38, 37], [-31, -22, -26], [-5, -1, 4], [-46, 8, -22, -11]]

Ex Output:

[0, -1100, -36, -224, 38, 572, 4, 8096]
