C++ :

#include <iostream>
using namespace std;
int main() {
    int input[6], arr[6];
    for (int i = 0; i < 6; ++i) {
        cin >> input[i];
    }
    for (int i = 0; i < 6; ++i) {
        arr[i] = input[5 - i];
    }
    for (int i = 0; i < 6; ++i) {
        cout << arr[i] << " ";
    }
    return 0;
}
