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:
[[42, -3, -11, -5, -36], [49, 41, -30, 34, 50], [-17, 20], [-21, 35, 23], [-28, 2, -10, 17, -42], [8, -24, -19, 34, -4], [28, 45, -12, -17], [44, -43, 32, -41], [-3, 4, 9], [-8, 44, -12, 27], [42, -50, 20], [19, 30]]
Answer:
[-1512, -51000, 20, 0, -23520, 26112, -336, 1408, 4, 4224, -42000, 30]
