System.out.println(Math.abs(total-total2));

}

}

}

 

正確答案為: 227031


答案差了一天 試問各位大大  是哪裡的問題呢  看了老半天看不出來

程式碼 我改成這樣  一樣有超時問題  

import java.util.Scanner;

 

 

public class a263 {

public static void main(String[] argv) {

// TODO Auto-generated method stub

Scanner sc = new Scanner(System.in);

 

while(sc.hasNext()) {

int []md ={0,31,28,31,30,31,30,31,31,30,31,30,31}; 

int year = sc.nextInt();

int month = sc.nextInt();

int date = sc.nextInt();

int judge=0;

 

int year2 = sc.nextInt();

int month2 = sc.nextInt();

int date2= sc.nextInt();

int judge2=0;

 

 

for(int i = 1 ; i < year ; i++) {

if(year % 4 == 0 && year % 100 != 0 || year % 400 == 0 && month>2 ) {

++judge;  

}else if(year2 % 4 == 0 && year2 % 100 != 0 || year2 % 400 == 0 && month>2) {

++judge2;                        //判斷到一次閏年+1

}

 

}

 

for(int i = 1 ; i < year ; i++) {

year+=365;

year2+=365;

}

month=0;

month2=0;

for(int i = 1 ; i < md.length ; i++) {

  month+=md[i-1];

  month2+=md[i-1];

}

 

                    int total = (year + month + date +judge)-(year2 + month2 + date2 +judge2);

 

 

System.out.println(Math.abs(total));

 

}

}

}
