Problem

An Impossible Foods packaging utility receives a label string and must identify whether the label is a palindrome. Write a function that returns True when the string reads exactly the same from left to right and right to left, and False otherwise.

Characters are case-sensitive, and spaces and punctuation are treated as ordinary characters. Do not modify the input string.

Formal Specification

Input: A string s containing zero or more ASCII characters.
Output: A Boolean value. Return True if s is a palindrome; otherwise, return False.

Use a two-pointer comparison so the function can stop as soon as a mismatched pair is found.

Constraints

0 <= len(s) <= 10^5
s contains only ASCII letters, digits, spaces, or punctuation
Comparisons are case-sensitive
Spaces and punctuation are significant
