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: [[-4, -31, 11, 39], [17, -7, -44, 3], [-17, 33, 18, -42], [-20, -13, -9, 48, -15]]
Example Output: [-4, -44, -756, -960]

Example Input: [[49, -7, 25, 42], [10, -10], [-22, 26, -34, 18, 6], [-34, 9, -33, 22, 45], [-14, -20, -13, -9], [14, 38, -45, -15, -10], [-28, 2, -27, 38], [-21, -49, -34, -13, 30], [16, 49, 48, 38], [2, 9, 13, 0, -5], [-27, -6, 16, -5, 46], [2, -43]]
Example Output: [42, -100, 2100384, -748, 280, -5320, -2128, -1020, 29184, 0, -4416, 2]

Example Input: [[23, -20, 23, 3], [-4, 11, 45, 43, -43], [19, 37, -15, 42]]
Example Output:
[-20, -4, 42]
