            for(i=0; i<3; i++){
                  for(j=1; j<4; j++){
                        i%=j;
			System.out.println(j);
		  }
	    }
      }

            if(i.equals(l)){
                  System.out.println("true");
            }else{

            switch(i){
                  case 0: System.out.println(0); break;
                  case 1: System.out.println(1);
                  case 2: System.out.println(2); break;
