Palindrome Number

Decide whether the decimal digits of n read the same forwards and backwards. Negative numbers are never palindromes because of the minus sign.

Implement is_palindrome_number(n).

Input

n: The number to check.

Output

Return true for a palindromic number, otherwise false.

Vincoli

-10¹⁸ ≤ n ≤ 10¹⁸
