#include <iostream>
using namespace std;

int main() {
    int a;
    long long int b;
    float c;
    char d;
    string e;
    while (cin >> a >> b >> c >> d >> e) { // 注意 while 处理多个 case
        cout << a << endl;
        cout << b << endl;
        printf("%.1f\n",c);
        cout << d << endl;
        cout << e << endl;
    }
}
// 64 位输出请用 printf("%lld")
