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: [[8, 39, -6, -41], [-24, -14, -29, -22], [36, 41, 42, -29], [2, -28]]

SOLUTION: [-48, -7392, 1512, -56]
