I need help with the extra-terrestrials challenge.

Answer 3

FYI, there is a reverse function in the Non-standard header;
#include <bits/stdc++.h>
And similarly in the header;
#include <algorithm>

Either, does an in place reversal of the string by passing in the begin and end iterators of the object.

reverse(userInput.begin(), userInput.end());
cout << userInput;
