Question

Create a recursive method, a method that calls itself, // that returns true or false depending on whether or not // a given string is a palindrome. A palindrome is a word // that reads the same forwards and backwards, such as // "tacocat"

Answer 1

Answer:

public class CheckPalindrome{

public static boolean IsPalindrome(String str){

if(str.Length<1)

{

return true;

}

else

{

if(str[0]!=str[str.length-1])

return false;

else

return IsPalindrome(str.substring(1,str.Length-2));

}

}

public static void main(string args[])

{

//console.write("checking palindromes");

string input;

boolean flag;

input=Console.ReadLine();

flag= IsPalindrome(input);

if(flag)

{

Console.WriteLine("Received"+input+"is indeed palindrome");

}

else

{

Console.WriteLine("received"+input+"is not a palindrome");

}

}
