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: [[-3, -41, 25, -18], [14, 50], [-10, -26, -42, 32, -25], [50, 23, 38], [-47, 31, -50, 30, 44], [-14, 36], [30, -4, -25, 33, 18], [-2, 39, -36, -17, 0], [-9, -50, 45, -10], [36, 30, 27, 40], [-11, 20, -28, 46, -38]]

Solution: [-18, 700, -349440, 1900, -66000, -504, -2160, 0, 500, 43200, 978880]
