Sample Solution:-

C# Sharp Code:

using System;

namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {
            Console.WriteLine(test("abc", "cat"));
            Console.WriteLine(test("python", "php"));
            Console.WriteLine(test("php", "php"));
            Console.ReadLine();
        }

 public static string test(string s1, string s2)
        {
             if (s1.Length < 1)
            {
                return s2;
            }

            if (s2.Length < 1)
            {
                return s1;
            }

            return !s1.EndsWith(s2.Substring(0, 1)) ? s1 + s2 : s1 + s2.Substring(1);
        }
   }
}

Sample Output:

abcat
pythonphp
phphp

Previous: Write a C# Sharp program to create a new string taking the first character from a given string and the last character from another given string. If the length of any given string is 0, use '#' as its missing character.
Next: Write a C# Sharp program to create a new string from a given string after swapping last two characters.
