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:
[[-15, 2], [36, -8, 23, -7], [15, 44, 25], [50, -32, 33, -27, -44], [-16, 40, -25, 46], [29, -9, 8, 49], [-15, 32], [-40, 45, -11, 29, -5], [-10, 36, 34, -32], [8, -33], [-23, -5, 26, 35, 44], [-26, -10, -7, 3], [6, 46], [-8, -16, 41, 31], [0, -33, 4, 36, -21]]
Answer:
[2, -288, 44, 70400, -29440, 8, 32, -40, 391680, 8, 1144, 260, 276, 128, 0]
