      int i=0; 
      int sum[]=new int[20]; 
      while(n1>0) { 
        sum[i]=n1%2; n1=n1/2; i++; 
      } 
      for(int a=i-1;a>=0;a--) { 
          System.out.print(sum[a]); 
      }  
   } 
   public static void main() { 
     int m,n,add; 
     adtbin ob=new adtbin(); 
     System.out.println("enter the value of m and n"); 
     m=sc.nextInt(); 
     n=sc.nextInt(); 
     add=m+n; 
     ob.fun(add); 
   }
