Solution

import java.io.*;
import java.util.*;

public class Solution {

    public static void main(String[] args) throws IOException {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
        String str = bufferedReader.readLine();
        String answer = "Yes";
        char left; char right;

        for (int i = 0; i < str.length() / 2; i++) {
            left = str.charAt(i);
            right = str.charAt(str.length() - 1 - i);

            if (left != right) {
                answer = "No";
            }
        }

        System.out.println(answer);
        bufferedReader.close();
    }
