解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class 一〇四九 {

    public static  int leap(int n) {

        if(n%4==0 && n%100!=0 || n%400==0) 

            return 366;

        else

            return 365;

    }

    public static int Feb(int n) {

        if(leap(n)==366)

            return 29;

        else

            return 28;

    } 

    public static void main(String args[]) {

        Scanner sc=new Scanner(System.in);

        int year=sc.nextInt();

        int month=sc.nextInt();

        int day=sc.nextInt();

        int sum=0;

        int days[]= {31,Feb(year),31,30,31,30,31,31,30,31,30,31};

        if(month==1) {

            sum=day;

            System.out.print(sum);

        }

        else {

            for(int i=0;i<month-1;i++) {

            sum+=days[i];

            }

            System.out.print(sum+day);

        }

    }
