这里用了输入流，并且继承了comparable的类进行排序，但是最后一个测试点仍然超时，暂时不清楚怎么解决

    		  int month=Integer.parseInt(time[1]);
    		  int day=Integer.parseInt(time[2]);

    		  if(age>0&&age<200) {
    			  people.add(person);
    		  }else if(age==0||age==200) {
    //			  年龄为0的和200的必须月份等于9，日期等于6
    			  if(month==9&&day==6) {
