Hello,

Please check the below code for the solution.

static void Main(string[] args)
{
    Console.WriteLine("Please enter text:");
    string Input = Console.ReadLine();

    Console.WriteLine();
    string[] wordsArr = Input.Split(' ');
    List lstPalindromeWords = new List();
    for (int i = 0; i < wordsArr.Length; i++)
    {
        string wordStr = wordsArr[i];
        string newStr = string.Empty;
        for (int j = wordStr.Length - 1; j >= 0; j--)
        {
            newStr = newStr + wordStr[j];
        }
        if (wordsArr[i].Trim().ToLower() == newStr.Trim().ToLower())
        {
            lstPalindromeWords.Add(wordsArr[i]);
        }
    }

    Console.WriteLine();
    Console.WriteLine("Output:");

    //Output
    for (int i = 0; i < lstPalindromeWords.Count; i++)
    {
        if (i < lstPalindromeWords.Count - 1)
            Console.Write(lstPalindromeWords[i] + ", ");
        else
            Console.Write(lstPalindromeWords[i] + ".");
    }
    Console.ReadLine();
}

public void Pallon()
{
    string oldval = "madam arora teaches malayalam";
    Console.WriteLine(oldval);
    Console.WriteLine();
    string[] oldArr = oldval.Split(' ');
    List lstnew = new List();
    for (int i = 0; i < oldArr.Length; i++)
    {
        string oldstr=oldArr[i];
        string newstr = string.Empty;
        for (int j = oldstr.Length-1; j >= 0; j--)
        {
            newstr = newstr + oldstr[j];
        }
        if (oldArr[i] == newstr)
        {
            lstnew.Add(oldArr[i]);
        }

    }

    //for Print The Output
    for (int i = 0; i < lstnew.Count; i++)
    {
        Console.Write(lstnew[i] + ' ');

    }
