Apartment Cleaning

You and your roommate are deciding whether to clean the apartment. The parameter yourMessiness represents how messy your side of the apartment is, and roommateMessiness represents how messy your roommate’s side is, both in the range from 0 to 20. The result is an int value indicating whether it’s time to clean. Return:

If either messiness is 5 or less (i.e., it’s still relatively clean), return 0 (no need to clean);
With the exception that if either messiness is 18 or more (i.e. the apartment is very messy), return 2 (definitely needs to clean);
Otherwise, return 1 (maybe).

Example Input	Expected Output
`shouldClean(4, 3)`	`0`
`shouldClean(4, 18)`	`2`
`shouldClean(6, 15)`	`1`

public class CleaningDecision
{
    public static int shouldClean(int yourMessiness, int roommateMessiness)
    {
        // Your Code Here //
    }

public static void main(String[] args)
    {
        System.out.println(shouldClean(4, 3)); // Output: 0

System.out.println(shouldClean(4, 18));  // Output: 2

System.out.println(shouldClean(6, 15)); // Output: 1
