Tests whether a string is a palindrome

  
#include <iostream>
#include <string>
#include <vector>

using namespace std;

bool is_palindrome(string s)
{
   if (s.length() <= 1) 
     return true;

   char first = s[0];
   char last = s[s.length() - 1];

   if (first == last){
      string subString = s.substr(1, s.length() - 2);
      return is_palindrome(subString);
   }
   else
      return false;

int main()
