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, 1], [-36, 36, -8, 24], [-46, 39, 9], [18, 45, 23, -43], [-43, 44, 43, -35, 10], [48, 44], [20, 47, -38], [-7, 17, 9, 6], [20, 35], [8, 23, -24, -46], [32, 32, 6], [23, 17], [12, 46, -42, -6], [-27, -49, -31]]
