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: [[7, -39, -8, -38, -50], [29, -39, -35, -40], [13, 2, -36, -37, -32], [12, -29, -22, 26], [-48, 35, -3], [4, 38, -42, 10]]
Example Output: [-15200, -40, 2304, -6864, -48, -63840]

Example Input: [[23, -22, 8], [-9, 49, -1], [-26, 18, -19], [6, 26, 30, 39, -32]]
Example Output: [-176, 0, -468, -149760]

Example Input: [[25, -40, 30], [-33, 9, 37, 30], [-47, -7, 22, 0, -50], [30, 33], [21, -49, 36], [-25, 36], [-44, -6, -23], [1, 6, 16, -29, 21]]
Example Output:
[-1200, 30, 0, 30, 36, 36, 264, 96]
