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: [[-41, -26, 2, -21], [-2, 18, -3, 2, 8], [-12, -34, -4, 46, 45]]
Example Output: [-52, -576, -75072]

Example Input: [[12, -6, -21, 33], [-8, -29, -44, 38], [-45, -21, 18], [8, -17, -26, 50], [0, 18, -38], [2, -24], [-8, 34, 25, -10]]
Example Output: [-72, 13376, 18, -10400, 0, -48, 2720]

Example Input: [[35, -14, 23, -21, -18], [29, 36, -7], [-30, -44, 25, 22], [-25, -26], [-35, -29, 29, -42, -16], [-17, -10, 22, -2, -47], [40, -3], [-9, 33], [-49, 12, -26], [15, -5, 32], [28, 38, 46], [30, -5, 31], [42, 17, -49, 48]]
Example Output:
[252, 36, 29040, -26, 672, 440, 40, 0, -312, 32, 48944, 30, 2016]
