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:
[[2, 31, 49], [7, -48], [-5, 16, 2, 28]]

Ex Output:
[2, -48, 896]


Ex Input:
[[49, 13], [32, 46], [32, -27, 10, 3, -15], [-45, -47], [-46, -28, 21]]

Ex Output:
[0, 1472, 320, 0, 1288]


Ex Input:
[[50, -44, -2], [-4, -41], [-14, -9], [24, 34], [35, -13, 3, 18], [-18, 40, 40, -23, -22], [-50, 13, 44, 9, -29], [-22, -31, 10, -29, 21], [37, 0], [-29, 32], [-49, 40, 13, -37, -18]]

Ex Output:

[4400, -4, -14, 816, 18, 633600, -2200, -220, 0, 32, -720]
