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: [[-6, -2, 20, 50], [31, -17, -31, -36, 39], [15, -26, -41], [21, -34, 50, -40, -36], [42, 22, -45, 32], [-39, 20, 31, 50, -36], [45, -1, -21, 44], [-2, 22, -17, 2, -22], [14, -49], [-12, 36, 40, 42, 41], [23, 32], [14, 13, 26, -39, 6], [32, -16, 7, 20, 5], [46, 29], [27, -44, -25]]
Example Output: [12000, -36, -26, -2448000, 29568, -36000, 44, 1936, 14, -725760, 32, 2184, -10240, 46, -44]

Example Input: [[10, -25, 29, -10], [-8, 31, 35, -48, -1], [-33, -29, 16], [3, -2], [-37, 19, -5, 16], [-34, -47, -33], [-30, 0, 37, 1], [-37, 45, 39, -5], [-47, 20, -20, -30, -29], [-37, -27, 46], [-17, -26, -35, 14], [-5, -38, -1, 35, 44]]
Example Output: [-100, 384, 16, -2, 16, -34, 0, 0, 12000, 46, -364, -1672]

Example Input: [[-50, -31, 19], [20, -21], [-41, -33, 4, -3, -1], [23, 30, 13], [13, 48, 21], [-18, 38, -21], [-16, 22, 0, -38, 3], [19, 25, 29, -4], [0, -16, 2, 37], [-21, 9]]
Example Output:
[-50, 20, 4, 30, 48, -684, 0, -4, 0, 0]
