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: [[31, -19, 33], [16, 10], [-32, -36, -23]]
Example Output: [0, 160, 1152]

Example Input: [[12, -6, -21, 33], [-8, -29, -44, 38], [-45, -21, 18], [8, -17, -26, 50], [0, 18, -38], [2, -24], [-8, 34, 25, -10]]
Example Output: [-72, 13376, 18, -10400, 0, -48, 2720]

Example Input: [[-50, -32, -2, -2], [24, -23, -45], [-22, -12], [22, 49], [-47, -43, 12, 6, -10], [-38, -49]]
Example Output:
[6400, 24, 264, 22, -720, -38]
