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: [[-26, 15], [46, -40, -18, 44, -29], [-4, -36, -17], [12, -22, 14, 13, -39], [-35, -41], [10, -7, 45, 9], [-39, -6]]
