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.

- $100≤N≤999$
- $N$ is an integer.

Input is given from Standard Input in the following format:

$N$

If $N$ is a palindromic number, print `Yes`

; otherwise, print `No`

.

575

Yes

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

.

123

No

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

.

812

No
