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: [[49, 17, -32, 34], [46, -39], [-25, -26, 20], [7, 26, 28, 33], [19, 13, -7], [-7, -15, -28, -48, 38], [-14, -45], [-3, 47, -24], [50, -22, 20, 26, -27], [-36, -32, 29, 50, 10], [-6, -28, -33, 28, -18], [-10, 38], [-25, 15, 39, 5, 47]]
