Closest Palindrome Number:

Write a function that returns the closest palindrome number to an integer.

If two palindrome numbers tie in absolute distance, return the smaller number.

Example:

closestPalindrome(887) ➞ 888

closestPalindrome(100) ➞ 99
// 99 and 101 are equally distant, so we return the smaller palindrome.

closestPalindrome(888) ➞ 888
//itself is a palindrome

closestPalindrome(27) ➞ 22

Notes:

If the number itself is a palindrome, return that number.
