Palindrome word can be read in both direction. Suppose “level” can be read in both direction, so it is palindrome word. To check palindrome word you can try like following code using C#.

    class Program
    {
        public static bool IsPalindrome(string word)
        {
            int minLength = 0;
            int maxLength = word.Length - 1;
            while (true)
            {
                if (minLength > maxLength)
                {
                    return true;
                }
                char a = word[minLength];
                char b = word[maxLength];
                if (char.ToLower(a) != char.ToLower(b))
                {
                    return false;
                }
                minLength++;
                maxLength--;
            }
        }

        static void Main()
        {
            string[] palindromeWord = {"aibohphobia","Dhaka","alula","cammac","Civic", "deified","deleveled",
                                 "detartrated","devoved","History","evitative","level","","mahedee"};

            foreach (string word in palindromeWord)
            {
                if (IsPalindrome(word))
                {
                    Console.WriteLine(word + " is a Palindrome");
                }
                else
                {
                    Console.WriteLine(word + " is not a Palindrome");
                }
            }
            Console.ReadKey();
        }
    }
