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

	int n,f,b,z,x;
	scanf("%d",&n);
	if(100<=n&&n<=999){
	
	b=n/100;
	z=(n/10)%10;
	x=n%10;
	f=(x*100)+(z*10)+b;
	if(f==n){
	
	cout<<"yes"; }
	else
	cout<<"no";
