write a program to print max and min palindrome word in a given string:

Solution:

using System;

namespace PalindromeMax
{
    class Program
    {

        public static void Main()
        {
            Console.WriteLine("Enter a string:");
            var str = Console.ReadLine();
            var word = string.Empty;
            var minPalindromeWord = string.Empty;
            var maxPalindromeWord = string.Empty;
            var words = new string[50];
            var wordCounter = 0;
            var count = 0;


            str += " ";

            foreach (var ch in str)
            {
                if (!char.IsWhiteSpace(ch))
                {
                    word += ch;
                }
                else
                {
                    words[wordCounter] = word;
                    wordCounter++;
                    word = string.Empty;
                }
            }

            for (var i = 0; i < wordCounter; i++)
            {
                if (!IsPalindrome(words[i])) continue;

                count++;
                if (count == 1)
                {
                    minPalindromeWord = maxPalindromeWord = words[i];
                }
                else
                {
                    if (minPalindromeWord.Length > words[i].Length)
                        minPalindromeWord = words[i];

                    if (maxPalindromeWord.Length < words[i].Length)
                        maxPalindromeWord = words[i];
                }
            }

            if (count == 0)
            {
                Console.WriteLine("No palindrome is present in string");
            }
            else
            {
                Console.WriteLine("Max palindromic: " + maxPalindromeWord);
                Console.WriteLine("Min palindromic: " + minPalindromeWord);
            }

            Console.ReadLine();
        }

        public static bool IsPalindrome(string str)
        {
            var isPalindrome = true;
            for (var i = 0; i < str.Length / 2; i++)
            {
                if (char.ToUpper(str[i]).Equals(char.ToUpper(str[str.Length - i - 1]))) continue;
                isPalindrome = false;
                break;
            }
            return isPalindrome;
        }
    }
}
