#include <iostream>
#include <string>
#include <iomanip>
using namespace std;

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