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: [[31, 43, 9, 3], [-27, 50, 18, -46], [15, -43], [25, 36, -48, -12, -23], [-14, -35, -41, -23, -30], [-12, -38], [38, -20], [-25, 5, 29], [25, 31, 45, -50], [35, 17]]
Example Output: [0, -41400, 0, 20736, 420, 456, -760, 0, -50, 0]

Example Input: [[23, -48, -18], [9, 47, 33, 32, -22], [-30, -23, 9, -25, -17], [-39, 8, 27], [3, -34, 8, -42]]
Example Output: [864, -704, -30, 8, 11424]

Example Input: [[-24, -6, -8, 18, 50], [-15, 37, 46], [32, 2, -44, 46, -15]]
Example Output:
[-1036800, 46, -129536]
