solution:

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
	Scanner in=new Scanner(System.in);
	String a=in.nextLine();
	char b[]=a.toCharArray();
	char c[]=new char[b.length];
	for(int i=b.length-1;i>=0;i--) {
		c[b.length-1-i]=b[i];
	}
	String c1=String.valueOf(c);
	if(c1.equals(a)) {
		System.out.println("yes");
	}
	else {
		System.out.println("no");
	}
	}
