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: [[-48, 11, -28, 10, 44], [30, -45], [40, 25, -42, -40], [-9, -44, -48, -21, 36], [-32, 16, -35, -26], [0, -49, 49], [30, -15, 0], [10, -16, -4], [-5, 38, -13, 17], [36, -34], [22, 6], [-28, -21], [37, 13, -41, -8, -37], [-22, -35]]
