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: [[-11, 26, -48, -18, -14], [-32, 10, -27, 15, -1], [-10, 9, 33, -46], [-4, 1, 40]]
