import java.util.Scanner;

public class demo1 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入一个年份:");
int year = scanner.nextInt();
if(year %4 == 0 && year % 100 != 0 || year % 400 == 0){
System.out.println(year+"是闰年");

}else {

System.out.println(year+"不是闰年");
}
}
}
