void main()

{

String s1, rev="";

IO.println("enter a string value");

Scanner s=new Scanner(System.in);

s1=s.nextLine();

int n=s1.length();

for(int i=n-1;i>=0;i--)

{

rev=rev+s1.charAt(i);

}

IO.println("the reverse is:"+rev);

if(s1.equals(rev))

{

IO.println("string is palindrome");

}

else

{

IO.println("string is not palindrome");

}

}
