算日期，直接用JAVA API搞定了，小偷个懒。。

import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Locale;import java.util.Scanner;public class Main{public static void main(String[] args){Scanner sc = new Scanner(System.in);Calendar c = Calendar.getInstance();int n;DateFormat df = new SimpleDateFormat("yyyy-MM-dd EEEE",Locale.US);while ((n = sc.nextInt()) != -1){c.set(2000, 0, 1);c.add(Calendar.DATE, n);System.out.println(df.format(c.getTime()));}}}
