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: [[-2, -17, -10], [-4, 9], [-32, -21], [42, 49, 41, -16, 7], [23, 8, -10], [9, -20, -34, 4], [-23, 48], [39, 35, -49], [-40, 50, 45], [-40, 21, -16, 31, 33], [-42, 5, 0], [16, 4, 41, -46], [-11, 40], [37, -28], [23, 28, -7, -28]]
