Problem

Change Healthcare systems may receive short identifier strings that require basic validation before processing. Given a string s, determine whether it is a palindrome, meaning it reads the same from left to right and right to left.

Compare characters exactly. The comparison is case-sensitive, and spaces, punctuation, and other characters are part of the string.

Formal Specification

Implement is_palindrome(s), where:

Input: s, a non-null string.
Output: Return True if s is a palindrome; otherwise, return False.

Use a two-pointer approach that compares characters from the beginning and end while moving toward the center.

Constraints

0 <= len(s) <= 10^5
s contains printable ASCII characters
Comparison is case-sensitive
Spaces and punctuation are significant
