Sample Solution:-

C# Sharp Code:

using System; // Import the System namespace which contains fundamental types and base classes
using System.Collections.Generic; // Import the System.Collections.Generic namespace for collections
using System.Linq; // Import the LINQ namespace for LINQ functionality
using System.Text; // Import the System.Text namespace for string manipulation
using System.Threading.Tasks; // Import the System.Threading.Tasks namespace for asynchronous operations

namespace exercises // Define a namespace called 'exercises'
{
    class Program // Define a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Output the result of test function with two strings as arguments
            Console.WriteLine(test("Hi", "Hello")); // Test with strings "Hi" and "Hello"
            Console.WriteLine(test("whats", "app")); // Test with strings "whats" and "app"
            Console.ReadLine(); // Wait for user input before closing the console window
        }

        // Function definition of test function that takes two strings 's1' and 's2' and returns a string
        public static string test(string s1, string s2)
        {
            return s1 + s2 + s2 + s1; // Concatenate s1, s2, s2, and s1 together and return the resulting string
        }
    }
}

Sample Output:

HiHelloHelloHi
whatsappappwhats
