C#: 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

C# Sharp Basic Algorithm: Exercise-86 with Solution

Remove 'a' if at Start or End

Write a C# Sharp program to create a string from a given string without the first and last character. This is if the first or last characters are 'a' otherwise return the original given string.

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Output the results of the test function with different strings as arguments
            Console.WriteLine(test("abcab")); // Pass "abcab" to the test function and display the result
            Console.WriteLine(test("python")); // Pass "python" to the test function and display the result
            Console.WriteLine(test("abcda")); // Pass "abcda" to the test function and display the result
            Console.WriteLine(test("jython")); // Pass "jython" to the test function and display the result
            Console.ReadLine(); // Wait for user input before closing the console window
        }

        // Function definition of the test function that takes a string 's1' as input and returns a string
        public static string test(string s1)
        {
            // If the length of 's1' is greater than 0 and the last character is "a", remove the last character
            if (s1.Length > 0 && s1.Substring(s1.Length - 1) == "a")
            {
                s1 = s1.Remove(s1.Length - 1);
            }

            // If the length of 's1' is greater than 0 and the first character is "a", remove the first character
            if (s1.Length > 0 && s1.Substring(0, 1) == "a")
            {
                s1 = s1.Remove(0, 1);
            }

            return s1; // Return the modified or unchanged 's1'
        }
    }
}

Sample Output:

bcab
python
bcd
jython

Previous: Write a C# Sharp program to create a new string from a given string without the first two characters. Keep the first character if it is "p" and keep the second character if it is "y".
Next: Write a C# Sharp program to create a new string from a given string. If the first or first two characters is 'a', return the string without those 'a' characters otherwise return the original given string.
