Bug Report for https://neetcode.io/problems/is-palindrome

based on my submissions, it should be wrong right? i don't add case for number but its still accepted

class Solution:
    def isPalindrome(self, s: str) -> bool:
        left = 0
        right = len(s) - 1
        lc_s = s.lower()

        while left < right:
            if ord(lc_s[left]) < 97 or ord(lc_s[left]) > 122:
                left += 1
            elif ord(lc_s[right]) < 97 or ord(lc_s[right]) > 122:
                right -= 1
            elif ord(lc_s[left]) != ord(lc_s[right]):
                return False
            else:
                left += 1
                right -= 1

        return True

I think the neetcode team need to add some usecase for that

suggestion testcase:
s = "5A"

expected result:
False
