Printing A Reversed Array of Integers

What this does is read integer by integer from cin and insert it at the beginning of a string variable. The string variable is then printed to cout. Another way to do this would be to create a vector, store the integers and then print it in reverse - but that would take two loops.

Sample Input:

5

2 3 4 5 7

Sample Output:

7 5 4 3 2

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

int main() {
    int n, p; cin >> n;
    string s;

    while (cin >> p) s.insert(0, (" " + to_string(p)));
    cout << s.substr(1, s.size()) << endl;

    return 0;
}
