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:
[[-4, -31, 11, 39], [17, -7, -44, 3], [-17, 33, 18, -42], [-20, -13, -9, 48, -15]]

Ex Output:
[-4, -44, -756, -960]


Ex Input:
[[0, -43, -36], [35, 22, -15, 14, -6], [-48, 42, 41, -41, 19], [11, -36, 1], [-3, -40, -50, -13], [26, -2, -44]]

Ex Output:
[0, -1848, -2016, -36, 2000, 2288]


Ex Input:
[[31, 37, 11], [-44, -36], [35, 37], [5, 26, 8, -38], [15, -1]]

Ex Output:

[0, 1584, 0, -7904, 0]
