Sample Solution:-

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {
            Console.WriteLine(test("abcab"));
            Console.WriteLine(test("python"));
            Console.WriteLine(test("press"));
            Console.WriteLine(test("jython"));
           
            Console.ReadLine();
        }
    public static string test(string s1)
          {
           if (s1.Length >= 2)
            {
                if (String.Compare(s1.Substring(1, 1), "y") != 0)
                {
                    s1 = s1.Remove(1, 1);
                }

                if (String.Compare(s1.Substring(0, 1), "p") != 0)
                {
                    s1 = s1.Remove(0, 1);
                }
            }
            else if (s1.Length > 0 && String.Compare(s1.Substring(0, 1), "p") != 0)
            {
                s1 = s1.Remove(0, 1);
            }

            return s1;
          }    
   }
}

Sample Output:

cab
python
pess
ython

Previous: Write a C# Sharp program to create a new string from a given string. If the two characters of the given string from its beginning and end are same return the given string without the first two characters otherwise return the original string.
Next: Write a C# Sharp program to create a new string from a given string without the first and last character if the first or last characters are 'a' otherwise return the original given string.
