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: [[-17, -33, 27, 45, -50], [10, 18, 25, 21], [20, -7, 10, -10, 19], [-8, -18, -11]]

SOLUTION: [-50, 180, -2000, 144]
