1005. Palindrome Strings

Palindrome strings

A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. This includes capital letters, punctuation, and word dividers.

Implement a function that checks if something is a palindrome. If the input is a number, convert it to string first.

Examples(Input ==> Output)

"anna"   ==> true
"walter" ==> false
12321    ==> true
123456   ==> false

Solution:

from typing import Union


def set_str(func):
    def wrapper(value: Union[str, int]):
        string = str(value)
        return func(string, len(string))
    return wrapper

@set_str
def is_palindrome(string: str, half_idx: int) -> bool:
    return string[:half_idx] == string[half_idx::-1]
