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: [[23, 38, 30, 36], [43, -3, 15], [-20, -25], [49, -38, -42], [24, -4], [-48, -41, -35], [-6, 36, -31, -42], [-48, 16, -47], [36, -40]]

Solution: [41040, 0, -20, 1596, -96, -48, 9072, -768, -1440]
