TASK DEFINITION: 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.
PROBLEM: [[-38, -29], [9, -32, 23, 9, -2], [48, 16, 16]]

SOLUTION: [-38, 64, 12288]
