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: [[13, -2, 13, -27], [-16, -8, 10], [-18, -23, -33, -50], [12, 0, -40, 21, -2], [35, 4, -39], [-50, 31, 0], [-5, -9, 27], [-48, 19], [43, 34, 6], [-15, -6, 2, -29, -47], [-28, -26, -29], [-43, -33, 24, 9], [16, -8], [10, -10, -40, -27, -37]]

Solution: [-2, 1280, 900, 0, 4, 0, 0, -48, 204, -12, 728, 24, -128, 4000]
