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:
[[-6, 46, 21], [-23, 40], [-31, 38, -24], [-23, -16, 6, 46], [-29, -43]]

Ex Output:
[-276, 40, -912, -4416, 0]


Ex Input:
[[-2, -17, -10], [-4, 9], [-32, -21], [42, 49, 41, -16, 7], [23, 8, -10], [9, -20, -34, 4], [-23, 48], [39, 35, -49], [-40, 50, 45], [-40, 21, -16, 31, 33], [-42, 5, 0], [16, 4, 41, -46], [-11, 40], [37, -28], [23, 28, -7, -28]]

Ex Output:
[20, -4, -32, -672, -80, 2720, 48, 0, -2000, 640, 0, -2944, 40, -28, -784]


Ex Input:
[[49, 29, 41, 50, -37], [40, 5, -49], [19, 34, -41, -34], [-30, -17, 2, -8, 42], [39, 15, -25, 34, -43], [50, -26, -18], [-16, -15, 46, -21]]

Ex Output:

[50, 40, -1156, 20160, 34, 23400, -736]
