Move Last Two Characters to Start

Write a C# Sharp program to move the last two characters to the start of a given string of length at least two.

Visual Presentation:

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")); // Test with the string "Hello"
            Console.WriteLine(test("JS"));    // Test with the string "JS"
            Console.ReadLine(); // Wait for user input before closing the console window
        }

        // Function definition of test function that takes a string 's1' and returns a string
        public static string test(string s1)
        {
            // Concatenate the substring from the second last character to the last character of 's1'
            // with the substring that removes the last two characters of 's1'
            return s1.Substring(s1.Length - 2) + s1.Remove(s1.Length - 2);
        }
    }
}

Sample Output:
