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

int main() {
    int n;
    while (cin >> n) { // 注意 while 处理多个 case
        int year = n/100;
        int month = n%100;
        if(month==1||month==2)
        month+=12;
        std::array<std::string, 4> jijie = {"spring", "summer", "autumn", "winter"};
        cout<<jijie[(month-3)/3];
        
    }
}
// 64 位输出请用 printf("%lld")

不想用ifelse，个人认为顺序使用数组方便一些
