Largest palindrome number

Write a function maxPalindromeNumber(numbers) that returns the largest palindrome number in an array. A palindrome number reads the same from left to right and from right to left, such as 7, 44 or 121.

• numbers is an array of integers. They can be positive, negative or 0.
• A number with one digit, also 0, is a palindrome.
• Negative numbers are not palindromes: -121 read from right to left is 121-.
• Return the largest palindrome as a number. It does not have to be the largest number of the array.
• If the array has no palindromes (also for an empty array), return null.
