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: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Example solution: [0, 72, -32]
Example explanation: The first inner list has no even integers, so the first number in the output is 0. The second list has -6, -6, 2 for even integers so the second output is 72. The third list has -8, 4 as even numbers so the third output is -32. This is a good example.

Problem: [[-28, 20], [2, -45, 17, -40, 2], [-30, -3, 49, 2, -38], [6, 15, -31, 23, -11], [-7, -3], [-19, 27, -49, -8, 47], [-21, -44, 34], [49, 21, 49, 7], [-36, 3, 36, -37]]

Solution: [-560, -160, 2280, 6, 0, -8, -1496, 0, -1296]
