Write a C# program to check if a given string is a palindrome or not

using System;
public class Example
{
   
    public static bool checkPalindrome(string inputString)
        {
          char[] c = inputString.ToCharArray();
          Array.Reverse(c);
          return new string(c).Equals(inputString);
        }
    public static void Main()
        {
             Console.WriteLine(checkPalindrome("aaa"));
             Console.WriteLine(checkPalindrome("abc"));
             Console.WriteLine(checkPalindrome("madam"));
             Console.WriteLine(checkPalindrome("1234"));
             
        }
}
