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:
[[-17, 10, 26], [23, 32, -20], [-49, -48], [-31, -48], [13, 37, -22], [43, 41], [-45, 49, -13, -27], [-19, 40, -46, 9, 49], [-33, -16], [-23, 34], [8, -5, 7, 17], [31, 50, 40, -17], [43, 43], [17, -2], [31, 25, -49, 41]]
Answer:
[260, -640, -48, -48, -22, 0, 0, -1840, -16, 34, 8, 2000, 0, -2, 0]
