#include<iostream>
#include<cstdlib>
using namespace std;

int main()
{
    int y;
 while(cin>>y){
  if(y>=0){
   if(y%400==0)
    cout<<"閏年"<<"\n";
   else if(y%100==0)
    cout<<"平年"<<"\n";
   else if(y%4==0)
    cout<<"閏年"<<"\n";
   else
    cout<<"平年"<<"\n";
  }
 }
 return 0;
}

我送出之後他說沒有明確範圍,沒有用while,但我改了之後還是找不出錯誤......
