#include <iostream>
using namespace std;

int main() {
    int a =0;
    cin >> a ;
    int b =a/10%10 + a%10;
    if(3<=b&&b<=5){cout << "spring" <<endl; };
    if(6<=b&&b<=8){cout << "summer" <<endl; };
    if(9<=b&&b<=11){cout << "autumn" <<endl; };
    if(1<=b&&b<=2||b==12){cout << "spring" <<endl; };
}
// 64 位输出请用 printf("%lld")
