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: [[-37, -17, -31, -47], [33, 45, 21, 44], [-16, -49, 14, -46], [19, -50], [-35, -40, 7], [29, 30, -21, -48], [-37, 20, -30, -27], [46, -27, -7]]
Example Output: [0, 44, 10304, -50, -40, -1440, -600, 46]

Example Input: [[45, -24, 39, -5, 39], [13, 1, 17, 19], [-10, 7, -30, 49, 19], [20, 5, -46], [8, 11, -1, -45, -50], [-14, -42], [21, 33, 3, -34], [-2, 7, -46, 15], [41, -19, 40]]
Example Output: [-24, 0, 300, -920, -400, 588, -34, 92, 40]

Example Input: [[-50, 41, 12, 41], [-24, 6], [-16, -13], [-41, -30, 40]]
Example Output:
[-600, -144, -16, -1200]
