Palindrome Integer**

Given an integer, check whether it is a palindrome. A palindrome is a number or a string that reads the same backward as forward.

Assume the numbers are positive.

Example


python
is_palindrome(121) == True
is_palindrome(123) == False
is_palindrome(1212) == False

def is_palindrome(n: int) -> bool:
    '''Checks if an integer is a palindrome.

    Arguments:
    n: int - the integer to check

    Return:
    bool - True if the integer is a palindrome, False otherwise
    '''
