Palindrome List Checker

You are given a list of integers. Your task is to determine whether the list is a palindrome. A list is considered a palindrome if it reads the same backward as forward.

The list can be empty, in which case it is considered a palindrome. You need to output the exact string "The list is a palindrome." if the list is a palindrome, otherwise output "The list is not a palindrome."

Note: The input will be given via standard input (stdin) and the output must be printed to standard output (stdout).

inputFormat

The first line contains an integer n representing the number of elements in the list.

If n is greater than 0, the second line contains n space-separated integers. If n is 0, then the list is empty.

outputFormat

Print a single line containing the string:

• "The list is a palindrome." if the list is a palindrome, or
• "The list is not a palindrome." if it is not.
