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-----
575

-----Sample Output-----
Yes

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