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

		public static void main(String[] args){
			
			Scanner sc = new Scanner(System.in);
			// 整数の入力
			// スペース区切りの整数の入力
			String a = sc.next();
			String[] strArray = a.split("");
			
			String b = strArray[3] + strArray[2] + strArray[1];
			
			if (a.equals(b)){
				System.out.println("Yes");
			    return;
