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: [[-40, -39], [-15, -29, -16], [-14, -39, -33], [-43, -20, -12, 21, 10], [50, -4, 47, -41, 0], [6, 15, -1, -11, -13], [-23, -9, -19], [19, 26, -34, -41, 24], [41, -29, -29], [28, -44, 22, -10], [17, -15], [41, 35, -11], [16, 45], [29, -4], [23, -41, -47, -39, -22]]
Example Output: [-40, -16, -14, 2400, 0, 6, 0, -21216, 0, 271040, 0, 0, 16, -4, -22]

Example Input: [[-50, -9, -21], [39, -39, -6, -13, -43], [34, 3, -48], [2, 42, 30], [-50, 10, -1, 1, -2], [-26, 3, 2]]
Example Output:
[-50, -6, -1632, 2520, 1000, -52]
