Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Calling the 'StringX' method with different strings and characters
            Console.WriteLine(StringX("xxHxix", "x"));   // Output: xHix
            Console.WriteLine(StringX("abxdddca", "a")); // Output: bxdddc
            Console.WriteLine(StringX("xabjbhtrb", "b"));// Output: xajhtr
            Console.ReadLine(); // Keeping the console window open
        }

        // Method to remove occurrences of a specific character 'c' except for the first and last occurrences in a string 'str1'
        public static string StringX(string str1, string c)
        {
            // Iterate through the characters in the string 'str1' starting from the second last character
            for (int i = str1.Length - 2; i > 0; i--)
            {
                // Check if the current character is equal to the given character 'c'
                if (str1[i] == c[0])
                {
                    // If so, remove that character from the string 'str1'
                    str1 = str1.Remove(i, 1);
                }
            }

            return str1; // Return the modified string 'str1'
        }
    }
}

Sample Output:

xHix
abxdddca
xajhtrb
