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: [[-21, -12, -13], [-37, -23, -6, -17], [14, -14], [23, 22, 34], [23, 15], [42, -42, 31, -50], [22, 44, -8, 13, -20]]
Example Output: [-12, -6, -196, 748, 0, 88200, 154880]

Example Input: [[35, 21, -23, 48, -16], [50, -50, -29, -3, -41], [46, -41, 2]]
Example Output: [-768, -2500, 92]

Example Input: [[-32, -29, 20, 40], [2, -35], [49, -46], [5, 34], [20, -14, -49], [26, 34], [27, 14, -18], [-37, -11, 11, -12, 7], [-9, -19, -47], [41, 0, 31, 15], [-1, -14, 26, 9], [36, -46, 17], [13, -34]]
Example Output:
[-25600, 2, -46, 34, -280, 884, -252, -12, 0, 0, -364, -1656, -34]
