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: [[-27, 11, -13, 21, -36], [-11, -15, -17, -24, 16], [12, 15, -3, 21, -4], [-28, -2, -38]]

SOLUTION: [-36, -384, -48, -2128]
