String Format s1s2s2s1

Write a C++ program to create another string using two given strings s1, s2, the format of the new string will be s1s2s2s1.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

// Function 'test' concatenates strings and creates a new string based on the input
string test(string s1, string s2)
{
    return s1 + s2 + s2 + s1; // Concatenates s1, s2, s2, and s1 in the given order
}

// Main function to test the 'test' function
int main() 
{
    // Displays the output of the 'test' function for different string inputs
    cout << test("Hi", "Hello") << endl;    // Output: "HiHelloHelloHi" (concatenation of strings)
    cout << test("whats", "app") << endl;   // Output: "whatsappappwhats" (concatenation of strings)
    return 0;    
}

Sample Output:

HiHelloHelloHi
whatsappappwhats
