        Scanner sc = new Scanner(System.in);

        for(int i=1;i<=7;i++){
            int week = sc.nextInt();

            switch(week){
                case 1:

                    System.out.println("星期一");

                    break;

                case 2:

                    System.out.println("星期二");
