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: [[19, 24, 49], [37, -15, -2, 31], [-20, -44, -12, 31, 39], [-47, 16, 19, -24, 6], [17, -15, 37], [-11, -21, 18, 29, 43], [8, -20, 47], [-8, -44, -24]]

Solution: [24, -2, -10560, -2304, 0, 18, -160, -8448]
