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, 42, -40, 28, -21], [-41, -14, -19], [-6, 34, 43, 38, 36]]

Ex Output:
[-47040, -14, -279072]


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

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


Ex Input:
[[27, -11], [2, -25, 11, -2, 19], [31, -12], [-50, -50, -18], [8, -24, -20], [-43, -14, 8]]

Ex Output:

[0, -4, -12, -45000, 3840, -112]
