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.

Let me give you an example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
The answer to this example can be: [0, 72, -32]
Here is 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.

OK. solve this:
[[-6, -27], [50, -8], [21, -43], [29, 45], [48, -25, -2], [22, 12, -49, -45, 20], [-9, 45], [-25, 17, -49, -43], [38, 12, -13, 49, -40], [40, -27], [1, 5, 18], [26, 47, -31, 21]]
Answer:
[-6, -400, 0, 0, -96, 5280, 0, 0, -18240, 40, 18, 26]
