C#: Check whether a given string starts with 'F' or ends with "B"

C# Sharp Basic Algorithm: Exercise-46 with Solution

Fizz, Buzz, FizzBuzz

Write a C# Sharp program to check whether a given string begins with "F" or ends with "B".
If the string starts with "F" return "Fizz" and return "Buzz" if it ends with "B" If the string starts with "F" and ends with "B" return "FizzBuzz".
In other cases return the original string.

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 'test' method with different strings and printing the results
            Console.WriteLine(test("FizzBuzz"));  // Output: FizzBuzz
            Console.WriteLine(test("Fizz"));      // Output: Fizz
            Console.WriteLine(test("Buzz"));      // Output: Buzz
            Console.WriteLine(test("Founder"));   // Output: Founder
            Console.ReadLine(); // Keeping the console window open
        }

        // Method to determine the output based on specific conditions in the input string
        public static string test(string str)
        {
            // Check if the string starts with "F" and ends with "B"
            if (str.StartsWith("F") && str.EndsWith("B"))
            {
                return "FizzBuzz";  // If both conditions are true, return "FizzBuzz"
            }
            // Check if the string starts with "F"
            else if (str.StartsWith("F"))
            {
                return "Fizz";      // If the string starts with "F", return "Fizz"
            }
            // Check if the string ends with "B"
            else if (str.EndsWith("B"))
            {
                return "Buzz";      // If the string ends with "B", return "Buzz"
            }
            else
            {
                return str;         // Return the original string if none of the conditions are met
            }
        }
    }
}

Sample Output:

Fizz
Fizz
Buzz
Fizz
