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: [[-37, 28, -2, -3], [-13, -6], [46, 11, -18, -31]]
Example Output: [-56, -6, -828]

Example Input: [[30, -24, -19, 29], [-1, -24], [26, 23, 27, 30, -23], [-17, 48, -43, 0], [40, -19, 21, 37], [37, -3], [-9, 24, 23, 36, -32], [-46, -13]]
Example Output: [-720, -24, 780, 0, 40, 0, -27648, -46]

Example Input: [[2, -40, 45], [-6, 36, 7, 50], [-38, -21], [-27, 5], [-16, -43, -12, -33], [42, 24, -39, 9, 4], [34, -42, -1, -40, -17], [27, 11, 23, -9], [49, -42, 8, 26, -34], [-18, 7, -46]]
Example Output:
[-80, -10800, -38, 0, 192, 4032, 57120, 0, 297024, 828]
