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.

Example Input: [[-10, -39, 40], [-5, 36, -28, 48], [5, -50, 31, 10, -16]]
Example Output: [-400, -48384, 8000]

Example Input: [[48, 41, 24, -29], [49, 22, -2, 27], [-39, 49, 37, 38, -29], [-18, 23, -5]]
Example Output: [1152, -44, 38, -18]

Example Input: [[26, 11, 35, -3], [32, -7, 12, 43], [14, -26, -45, 2, -43], [-10, 3, 9, 7, -26], [15, 27], [0, 15], [-31, -4]]
Example Output:
[26, 384, -728, 260, 0, 0, -4]
