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: [[-37, 48, 1, -15], [-10, 47, 32, -22, -30], [-38, 19, 4, -47], [-45, -4, 32, 40], [0, 38, -38], [-50, 32, 0, 29], [20, 26, 45, -29], [-45, 18, 17, -43, -27]]
Example Output: [48, -211200, -152, -5120, 0, 0, 520, 18]

Example Input: [[-1, -12], [-8, -2, 19, -47, -49], [-18, 25], [10, -20, 4], [-39, 20, 7], [11, 12, -37], [14, -49], [-18, -44], [48, 4, -23, 44], [37, 11, -4, -30, 12], [-18, 36], [19, 40, 47, -26, 44], [-13, -30, 44, 24, 21], [-49, 30, -39, 48]]
Example Output:
[-12, 16, -18, -800, 20, 12, 14, 792, 8448, 1440, -648, -45760, -31680, 1440]
