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:
[[0, 50, 16, -48, 7], [-2, -21, 12, 44], [20, -45, 14, 47], [-48, 10, -17, 34, 21]]

Ex Output:
[0, -1056, 280, -16320]


Ex Input:
[[41, -20, -31, 40, 22], [-16, 10, 16, 25, 24], [18, 28, 33, -41], [8, 48, -39, -31], [-27, 9]]

Ex Output:
[-17600, -61440, 504, 384, 0]


Ex Input:
[[-25, 22, -24, -16], [-47, 21], [31, 21, -2], [30, 19, 2, 28], [33, 46, 20], [-29, -33, -45, -41, -16], [-41, 6, -42], [42, -4], [-25, 10], [13, 33, -7], [6, -37], [-48, -32, -22], [29, 1, 5, 47]]

Ex Output:

[8448, 0, -2, 1680, 920, -16, -252, -168, 10, 0, 6, -33792, 0]
