水题, 代码如下:

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Main {

    public static void main(String[] args) throws Exception{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        int day = Integer.parseInt(br.readLine());
        if (day <= 5) {
            System.out.print(day+2);
        } else if ( day>5 && day<=7) {
            if (day == 6) {
                System.out.print(1);
            } else {
                System.out.print(2);
            }
        } else {
            return;
        }

    }

}
