//Program to check given string is palindrome (or) not.

import java.util.*;
class palindrome
     {
   public static void main(String args[])
      {
        String s;
    Scanner in=new Scanner(System.in);
    System.out.println(" Enter your text: ");
    s=in.nextLine();
    char a[]=s.toCharArray();//converting string to array.
        int i=0,is_palin=1,j=a.length;//j stores the length of array.
        for(i=0,j=j-1;i<j;i++,j--)
          {
           if(a[i]!=a[j])
             {
               is_palin=0;
               break;
             }
          }
    if(is_palin==1)
       {
        System.out.println("It is palindrome");
       }
    else
        {
          System.out.println(" It is not palindrome");
        }
      }
    }
