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: [[-37, 28, -2, -3], [-13, -6], [46, 11, -18, -31]]

SOLUTION: [-56, -6, -828]
