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: [[-5, 29, 5, 36], [36, -42], [36, -14, 49, 28, -33], [-39, 4], [-46, 44, 37], [-10, -36, -35, 24], [7, 10], [28, 23, 30], [-42, 4, -50], [-1, -2, 50], [-3, -42, 3], [-5, -45, 28], [-43, -8, -18], [-37, -42, 17], [30, 32, 39]]
