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, -21], [25, 29, 18, -18], [6, 48, -5, 43], [36, 41], [-44, -30, 5, -24], [12, 13, 28, -44], [3, -32], [12, 31, -13, 2, 8], [11, -4, 2, -46, 45], [20, -43, -26], [-44, -14, 32, -13, -46]]
