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, -20, 18, -43, 7], [-49, -13, 11], [-29, -31], [-9, 6, -6], [3, 44, 33, -15, 20], [31, 20, 4, 49, -22]]

Ex Output:
[-360, 0, 0, -36, 880, -1760]


Ex Input:
[[-39, 28, -32, -7, 24], [-19, 0, 30, 25, 41], [-17, -20, -31, -9], [13, -6], [-5, -23, -4, 19, 47], [-40, -26, 17, -9]]

Ex Output:
[-21504, 0, -20, -6, -4, 1040]


Ex Input:
[[19, -39, -20], [4, 18, 16, -20, -39], [8, -42, -17, -43], [30, 19, -14, -17]]

Ex Output:

[-20, -23040, -336, -420]
