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: [[18, 17], [-48, 16, 17, 1], [-14, 26, -17], [17, 49, -30, -42, 26], [-20, 16, -4, -5, 4], [-39, 23, -37, -25], [24, -40, -23, -4]]
Example Output: [18, -768, -364, 32760, 5120, 0, 3840]

Example Input: [[-43, -45, 10], [39, 26, -49, -49, -8], [47, 21, 42], [-47, 29, -18]]
Example Output:
[10, -208, 42, -18]
