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: [[14, -13, 19], [-16, 38], [21, -7, 18, -48], [-38, -46, 20], [-15, -13, 29], [7, -15, 38, -32, -41], [-23, -13, -35, -39, 3], [-27, -44], [21, -33], [40, -33, -30, -7, 21], [-29, -33, 0], [-33, -21, -13, 13, 12], [34, 28, 36, 24]]
