Is 131 a numerical palindrome?
The first 30 palindromic numbers (in decimal) are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, … (sequence A002113 in the OEIS).

Which is the closest palindrome in the range?
The closest is defined as the absolute difference minimized between two integers. Input: n = “1” Output: “0” Explanation: 0 and 2 are the closest palindromes but we return the smallest which is 0. n consists of only digits. n does not have leading zeros. n is representing an integer in the range [1, 10 18 – 1].

Do you take the mirror of the left side of a palindrome?
To convert to palindrome, we can either take the mirror of its left half or take mirror of its right half. However, if we take the mirror of the right half, then the palindrome so formed is not guaranteed to be the closest palindrome. So, we must take the mirror of left side and copy it to right side.
