C++ Basic Algorithm: Exercise-59 with Solution

Write a C++ program to create a new string using three copies of the last two character of a given string of length atleast two.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string test(string s1)
         {
            string last2 = s1.substr(s1.length() - 2);
            return last2 + last2 + last2;
         }       
       
int main() 
 {
  cout << test("Hello") << endl;  
  cout << test("Hi") << endl;  
  return 0;
