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: [[6, 32, -28, 48], [-15, 23, 26, -43, -21], [34, 1], [42, 37, -21, 29], [-19, -22, -26, 2], [37, -25, 4, -23], [31, -39], [16, -20], [6, -19]]

Solution: [-258048, 26, 34, 42, 1144, 4, 0, -320, 6]
