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: [[28, 27, -47, -20, 12], [13, 33], [10, 5, 28, 45], [-29, 42, -28, -47, -34], [43, -43, 45, -23, 10], [-15, -34, 38], [-48, 10], [42, 3, 46, -1, -50], [7, -45, 36, 5, -37], [-7, -28, -49, 33], [11, -17, 13, -3]]

SOLUTION: [-6720, 0, 280, 39984, 10, -1292, -480, -96600, 36, -28, 0]
