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:
[[17, -18, 9], [-42, -12], [39, -2, 31, 14], [-16, -9, -20], [19, -30], [47, -29, -40]]

Ex Output:
[-18, 504, -28, 320, -30, -40]


Ex Input:
[[-46, 5, -43, -49], [-8, 21, 15], [17, -27, -50, 40, -34], [49, 25, -33], [32, 6, -27, 26], [0, 30]]

Ex Output:
[-46, -8, 68000, 0, 4992, 0]


Ex Input:
[[31, 40, 4, 32, 2], [-4, -31, -32, -7, -35], [-1, 46, 13], [49, -26, 32], [-22, 48], [40, -48, -49, -34], [50, -44, 48], [-44, -26, -50], [-35, -4, 47, 25], [50, 13, -1, -4], [25, -26, -22, -5]]

Ex Output:

[10240, 128, 46, -832, -1056, 65280, -105600, -57200, -4, -200, 572]
