Format Long+Short+Long Strings

Write a C# Sharp program to create a new string from two given strings, one of which is shorter and one of which is longer. The new string format will be long string + short string + long string.

Sample Solution:-

C# Sharp Code:

using System; // Import the System namespace which contains fundamental types and base classes

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 the test function with different strings as arguments
            Console.WriteLine(test("Hello", "Hi"));    // Test with strings "Hello" and "Hi"
            Console.WriteLine(test("JS", "Python"));   // Test with strings "JS" and "Python"
            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)
        {
            // Check if the length of 's1' is less than the length of 's2'
            // If true, concatenate 's2', 's1', and 's2'
            // If false, concatenate 's1', 's2', and 's1'
            return s1.Length < s2.Length ? s2 + s1 + s2 : s1 + s2 + s1;
        }
    }
}

Sample Output:

HelloHiHello
PythonJSPython
