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: [[-5, -48, -19], [0, -49, -41], [18, -18, -32, 47], [37, -50, -4], [48, -38, -29, -39], [-8, 34, 12, 35], [31, -5, 14, 9], [0, -26], [-47, -40, -40, -46], [-4, -15, 50, -28]]

Solution: [-48, 0, 10368, 200, -1824, -3264, 14, 0, -73600, 5600]
