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

Example Input: [[-29, 37, -20], [13, 17, 13, -33, 2], [-8, 34, -44]]
Example Output: [-20, 2, 11968]

Example Input: [[36, 50, 28, -35], [-7, 34], [40, 4], [0, 37, -16], [-8, 16, -32], [25, 17, 20, -13]]
Example Output:
[50400, 34, 160, 0, 4096, 20]
