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:
[[-39, -3, -36, 0], [31, 3, -24], [-3, 38, 21, -48], [-21, -18, 35], [41, 16, 22], [40, -38, 2], [2, -1, 26, 30], [-13, 16], [11, 1], [-28, 42, -40, 13], [1, -50, 10, 38, 37]]
Answer:
[0, -24, -1824, -18, 352, -3040, 1560, 16, 0, 47040, -19000]
