You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

[[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution: [0, 72, -32]
Why? 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.

New input: [[18, -12, -40, 14, 21], [-44, -31], [-35, -36, 11, 39], [-31, -6, 40], [30, 43, 26, -14, 14], [-39, 32, -32, -20], [-8, -35, -31, 2, 37], [-19, 34], [-11, 45], [26, -26, -4, 18], [-23, -25], [-17, -3, -13, 21, -24], [-5, 9], [20, 45, 29, 49, 28], [30, -42]]
Solution:
[120960, -44, -36, -240, -152880, 20480, -16, 34, 0, 48672, 0, -24, 0, 560, -1260]
