C# Sharp: Basic Algorithm Exercises - Create a new string  where 'if' is added to the front of a given string

Sample Solution:

C# Sharp Code:

using System;
namespace exercises
{
     class Program
    {
      static void Main(string[] args)
        {
            Console.WriteLine(test("if else"));
            Console.WriteLine(test("else"));
            Console.ReadLine();
        }
        
       public static string test(string s)
        {
            if (s.Length > 2 && s.Substring(0, 2).Equals("if"))
            {
                return s;
            }
            return "if " + s;
        }
  }
}
