C#: Longest abecedarian word in a array of words

Last update on December 20 2024 12:44:27 (UTC/GMT +8 hours)

Abecedarian Word:
The English noun and adjective abecedarian has several closely related senses. As a noun, it means "someone learning the letters of the alphabet," and more loosely, "a beginner in a field of learning." As an adjective, abecedarian means "pertaining to the alphabet; arranged in alphabetical order; elementary, rudimentary."

Write a C# Sharp program to find the longest abecedarian word in a given array of words.

Sample Data:
({"abc", "abcd", "abcdef", "pqrstuv"}) -> "pqrstuv"
({"abc", "abcd", "abcdef", "pqrs"}) -> "abcdef"
({}) -> "Empty array!"

Sample Solution:

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    class Program
    {
        static void Main(string[] args)
        {
            // Declare and initialize an array of words
            string[] words = {"abc", "abcd", "abcdef", "pqrstuv"};

            // Display the original array of words
            Console.WriteLine("Original array of words: ");
            Console.WriteLine($"{string.Join(", ", words)}");

            // Display the longest abecedarian word in the array
            Console.WriteLine("Longest abecedarian word in the said array of words: " + test(words));

            // Change the array of words
            string[] words1 = {"abc", "abcd", "abcdef", "pqrs"};

            // Display the new original array of words
            Console.WriteLine("\nOriginal array of words: ");
            Console.WriteLine($"{string.Join(", ", words1)}");

            // Display the longest abecedarian word in the array
            Console.WriteLine("Longest abecedarian word in the said array of words: " + test(words1));

            // Change the array of words to an empty array
            string[] words2 = {};

            // Display the new original array of words (empty)
            Console.WriteLine("\nOriginal array of words: ");
            Console.WriteLine($"{string.Join(", ", words2)}");

            // Display a message for an empty array or the longest abecedarian word in the array
            Console.WriteLine("Longest abecedarian word in the said array of words: " + test(words2));
        }

        // Define a method 'test' that takes an array of strings 'array_words' and returns a string
        public static string test(string[] array_words)
        {
            // Check if the array is empty
            if (!array_words.Any())
            {
                return "Empty array!";
            }

            // Initialize an empty string to store the result
            string result = "";

            // Iterate through each word in the array
            foreach (string word in array_words)
            {
                // Convert the word to a character array and sort it
                char[] temp = word.ToCharArray();
                Array.Sort(temp);

                // Create a string from the sorted characters
                string cword = new string(temp);

                // Check if the sorted word is equal to the original word and its length is greater than the current result's length
                if (cword == word && word.Length > result.Length)
                    result = word;
            }

            // Return the longest abecedarian word found in the array
            return result;
        }
    }
}

Sample Output:

Original array of words: 
abc, abcd, abcdef, pqrstuv
Longest abecedarian word in the said array of words: pqrstuv

Original array of words: 
abc, abcd, abcdef, pqrs
Longest abecedarian word in the said array of words: abcdef

Original array of words: 

Longest abecedarian word in the said array of words: Empty array!
