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: [[-39, 26], [-10, 42, -49, -26, 49], [-47, -44, 32], [36, 40, -20, -16], [3, 22, 8], [-18, -25, 6, 45, -50], [-12, -37, 35], [22, -12, -49], [13, 19], [-22, -30], [-46, -6], [-10, 10, 35], [25, -1, -8], [26, -12, 49, -40, -14], [34, -32]]
