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: [[4, 48, 11, -29, -42], [2, -23, -18], [-7, -27], [-43, -18, -34, 16]]

SOLUTION: [-8064, -36, 0, 9792]
