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: [[0, -14, 2, 35, -25], [-21, -38, 22, -39, 3], [-13, -47, 34, 50]]
Example Output: [0, -836, 1700]

Example Input: [[-42, -43, -28, 45], [-27, 20, 46, -25, 9], [40, -46, 29], [19, 42], [-5, 30, 30], [14, 47, 13, 35], [-15, -29, 39, 0], [26, -44]]
Example Output: [1176, 920, -1840, 42, 900, 14, 0, -1144]

Example Input: [[15, -47, 28, -25], [19, -27, 7], [36, -38], [-36, 0, 49, 23, 34], [35, -31, -24, -44, -1], [-7, 3, 48, 7]]
Example Output:
[28, 0, -1368, 0, 1056, 48]
