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:
[[32, -48, -17], [-22, 28], [11, 2]]

Ex Output:
[-1536, -616, 2]


Ex Input:
[[46, 38, -30, 12, 35], [41, 47, -23, 30, 14], [21, -9], [-39, 45, 37], [33, -21, 25, 33], [-47, -29, -14], [-37, 3, 48, 39], [1, -5, 27, 45, -4], [-36, -3, -33, 21], [44, 1, -8, -27], [-27, 16, -47], [30, -37, -36, 4, 43], [-8, 6, 19]]

Ex Output:

[-629280, 420, 0, 0, 0, -14, 48, -4, -36, -352, 16, -4320, -48]
