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:
[[-13, 30, 21], [23, 40, -19], [-8, -49], [-30, -48, 43], [26, 20], [38, -11, 24, 15, -48], [-39, 10, -22, -48, -25], [2, 23, 33, 3], [38, -10, -40, 49, 5], [-20, 31, -20, -12, -43], [6, 22, -41, -14, 43], [5, 13], [-9, 46, 37, -28, -5], [31, -5, 38, 33, 33]]
Answer:
[30, 40, -8, 1440, 520, -43776, 10560, 2, 15200, -4800, -1848, 0, -1288, 38]
