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

Ex Output:
[-56, -6, -828]


Ex Input:
[[-32, 1, 1, -48], [-36, -24, -4, -36, 11], [18, -45], [-7, 25, -29, -6], [-39, -36], [44, -44, 0, 1, -49], [9, 32, -33, -34], [26, -18, -38, 48, 1], [-16, 10, 49]]

Ex Output:
[1536, 124416, 18, -6, -36, 0, -1088, 853632, -160]


Ex Input:
[[-12, 24, 24, 5], [13, 30, 26, 23], [23, 20, 14, -49]]

Ex Output:

[-6912, 780, 280]
