import java.util.Calendar; import java.util.Scanner;

public class Main { public static void main(String[] args) { Scanner console = new Scanner(System.in); int year = console.nextInt();

    //write your code here......
    Calendar calendar = Calendar.getInstance();
    for (int i = 0; i < 12; i++) {
        calendar.set(year, i, 1);
        System.out.printf("%d年%d月:%d天\n",
                          year,
                          i+1,
                          calendar.getActualMaximum(Calendar.DAY_OF_MONTH));
    }

}
