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.

[[8, 39, -6, -41], [-24, -14, -29, -22], [36, 41, 42, -29], [2, -28]]
[-48, -7392, 1512, -56]

[[-41, -34, -7, -18], [-43, -33, 8], [33, 12, -19]]
[612, 8, 12]
