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.

[[-11, 18, -12, -30, 23], [-18, 33, 40, -18, 19], [-16, -5, -43], [-34, -49]]
[6480, 12960, -16, -34]

[[23, 12, 35, -33], [6, -37, -14, 23], [-25, -14], [12, -50, 11, -38, 36]]
[12, -84, -14, 820800]

[[9, -3, -35, -21], [20, 11, 39, 34], [17, 11], [6, -25, -48], [39, 8], [25, -1], [33, 47, 42], [-48, 39, 0, -47], [36, 36]]

[0, 680, 0, -288, 8, 0, 42, 0, 1296]
