import java.util.*;
public class Superstring
{
      public static void main(String[] args)
      {
        int a=0,b=0;
        String sen="";
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the string to be 
        checked:");
        sen=sc.nextLine();
        for(int i=0;i<sen.length();i++)
        if (sen.charAt(i)>='a' && sen.charAt(i)<='z')
            a++;
        for(int i=0;i<sen.length();i++)
        if (sen.charAt(i)>='A' && sen.charAt(i)<='Z')
            b++;
if (a=b)
       System.out.println("String entered is a
       Superstring");
else
      System.out.println("String entered is a not a
      Superstring");
    }
}
