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: [[-10, 39, -31, 2], [-45, 4, 34], [-19, 25, 47, -4], [15, -3], [-10, 18, 50, 30]]
Example Output: [-20, 136, -4, 0, -270000]

Example Input: [[47, 22, 8], [15, 11, -26, 24], [-26, 19], [-24, 40, -36, -12], [37, -3, -45, -6], [40, 23], [12, -47, -48], [-38, -26, 20, -3, 10]]
Example Output: [176, -624, -26, -414720, -6, 40, -576, 197600]

Example Input: [[5, -42], [-39, 46, 9, -35], [-21, 0], [-32, -48, -24], [-34, 34, 17], [14, 27, 28, 11, 0], [11, 0, 25, 29, -28], [-33, -40, -49], [13, 9, -24], [15, -6, 38, -33, -2], [-20, -23, 42], [26, -13, 17, -18, -37], [37, -43]]
Example Output:
[-42, 46, 0, -36864, -1156, 0, 0, -40, -24, 456, -840, -468, 0]
