using namespace std;

int main(){
	ios_base::sync_with_stdio (false);
	cout << fixed;
	cout.precision(10);
	if(fopen("joke.in", "r")){
		freopen ("joke.in","r",stdin);
		freopen ("joke.out","w",stdout);
	}
	
	vector<string> s(3);
	s[0] = "Sunny";
	s[1] = "Cloudy";
	s[2] = "Rainy";

	string x;
	cin >> x;

	if(s[0].compare(x) == 0){
		cout << s[1];
	}else if(s[1].compare(x) == 0){
		cout << s[2];
	}else{
		cout << s[0];
	}

    return 0;
