Solution:
import java.util.*;
public class Main
{
   public static void main(String[]args)
   {
     Scanner in=new Scanner(System.in);
     int n=in.nextInt();
     if(n<=10)
     {
       if(n%2!=0)
         System.out.println("Red");
       else
          System.out.println("Black");
     }
     else if(n>=11&&n<=20)
     {
     
       if(n%2!=0)
         System.out.println("Black");
       else
