A11223. Quasi-palindrome

编程题 普及/提高-

题目描述

Let quasi-palindromic number be such number that adding some leading zeros (possible none) to it produces a palindromic string.

String $t$ is called a palindrome, if it reads the same from left to right and from right to left.

For example, numbers $131$ and $2010200$ are quasi-palindromic, they can be transformed to strings " $131$ " and " $002010200$ ", respectively, which are palindromes.

You are given some integer number $x$ . Check if it's a quasi-palindromic number.

输入格式

The first line contains one integer number $x$ ( $1<=x<=10^{9}$ ). This number is given without any leading zeroes.

输出格式

Print "YES" if number $x$ is quasi-palindromic. Otherwise, print "NO" (without quotes).
