Given a string n representing an integer, return the closest integer (not including itself), which is a palindrome. If there is a tie, return the smaller one.

\n\n

The closest is defined as the absolute difference minimized between two integers.

\n\n

 

\n

Example 1:

\n\n
\nInput: n = "123"\nOutput: "121"\n
\n\n

Example 2:

\n\n
\nInput: n = "1"\nOutput: "0"\nExplanation: 0 and 2 are the closest palindromes but we return the smallest which is 0.\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "寻找最近的回文数", "translatedContent": "

给定一个表示整数的字符串 n ，返回与它最近的回文整数（不包括自身）。如果不止一个，返回较小的那个。

\n\n

“最近的”定义为两个整数差的绝对值最小。

\n\n

 

\n\n

示例 1:

\n\n
\n输入: n = \"123\"\n输出: \"121\"\n
\n\n

示例 2:

\n\n
\n输入: n = \"1\"\n输出: \"0\"\n解释: 0 和 2是最近的回文，但我们返回最小的，也就是 0。\n
\n\n
