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.
Example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Example solution: [0, 72, -32]
Example explanation: 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.

Problem: [[-41, -8, -13], [-8, 31, 43], [3, 31, -8, 44, -7], [28, -39, 42, -35], [-18, -26, 17], [-34, 21, 18], [36, 29, -5], [27, 7], [-41, 21]]

Solution: [-8, -8, -352, 1176, 468, -612, 36, 0, 0]
