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.

[[-37, 28, -2, -3], [-13, -6], [46, 11, -18, -31]]
[-56, -6, -828]

[[24, -35, -32], [-12, 35, 13, 39], [22, 10, 40, -50, -44]]
[-768, -12, 19360000]

[[2, 28, 28], [-16, 19, 30], [-45, 19, -3, -45, 42]]
