How do you check if a given string is a palindrome?

How do you check if a given string is a palindrome?

Example  

Input : madam

Output : palindrome

Input : madam

Output : Not a palindrom

Solution:

Step’s

·         First do some validation

·         Store the string in a char array

·         Using loop store reverse string in another string

·         Compare the both string

public static void Palindrom(string str)

        {

            if ((str == null) || (str.Length <= 1))

                Console.Write(str);

            else

            {

                str = str.ToUpper();

                char[] chr = str.ToCharArray();

                string str2 = "";

                for (int i = chr.Length - 1; i >= 0; i--)

                {

                    str2 += chr[i];

                }

                if (str.Equals(str2))

                {

                    Console.Write("String " + str + " is palindrom ");

                }

                else

                {

                    Console.Write("String " + str + " is Not a palindrom ");

                }

               

            }

        }

static void Main(string[] args)

        {

            Console.WriteLine("=============================================================================");

            Console.WriteLine("How do you check if a given string is a palindrome?");

            Console.WriteLine("=============================================================================");

            Program objprog = new Program();

            Program.Palindrom("madam");

            Console.ReadLine();

        }
