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: [[-28, -15, -33, 39, 14], [43, -8], [36, -42], [49, -29, 48, 28, -11], [24, 33], [-39, -6, 34, -15], [-13, -47], [5, 38, -26], [30, 28], [13, -30, -39, -14, 29], [-20, 46, -11, 25, 5], [40, -16]]

Solution: [-392, -8, -1512, 1344, 24, -204, 0, -988, 840, 420, -920, -640]
