 import java.util.*;

class WordPalindorome

{

public static void main(String[] args)

{

int div=0 ,n;

Scanner sc = new Scanner(System.in);

System.out.println(" enter the word");

String s = sc.nextLine();

char str[]=s.toCharArray();

n= str.length;

for(int i =0;i<n;i++)

{

if(str[i]!=str[n-i-1])

{

div++;

break;

}


}

if(div == 0)

{

System.out.println("hai");
