Problem Statement

You are given a three-digit positive integer N.

Determine whether N is a palindromic number.

Here, a palindromic number is an integer that reads the same backward as forward in decimal notation.

Constraints

100≤N≤999

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N is a palindromic number, print Yes; otherwise, print No.

Sample Input 1

575

Sample Output 1

Yes

N=575 is also 575 when read backward, so it is a palindromic number. You should print Yes.

Sample Input 2

123

Sample Output 2

No

N=123 becomes 321 when read backward, so it is not a palindromic number. You should print No.

Sample Input 3

812

Sample Output 3

No

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String num = br.readLine();
		int n = Integer.parseInt(num);
		int x = n / 100;
		int z = n % 10;

		if (x == z) {
			System.out.println("Yes");
		} else {
			System.out.println("No");
