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.

[[0, -14, 2, 35, -25], [-21, -38, 22, -39, 3], [-13, -47, 34, 50]]
[0, -836, 1700]

[[-31, 42, -40, 28, -21], [-41, -14, -19], [-6, 34, 43, 38, 36]]
[-47040, -14, -279072]

[[2, 0, 20, 29], [-18, -42, -43, 2], [13, 48, -2]]

[0, 1512, -96]
