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.
One example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution is here: [0, 72, -32]
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.

Now, solve this: [[46, 28, -1], [40, -12, 30, -39, -25], [35, -26, -28, 10, 48], [-40, 8]]
Solution:
[1288, -14400, 349440, -320]
