564 - Find the Closest Palindrome.

Hard

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.

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

Example 1:

Input: n = “123”

Output: “121”

Example 2:

Input: n = “1”

Output: “0”

Explanation: 0 and 2 are the closest palindromes but we return the smallest which is 0.

Constraints:

• 1 <= n.length <= 18
• n consists of only digits.
• n does not have leading zeros.
• n is representing an integer in the range [1, 1018 - 1].
