Problem

A General Motors vehicle diagnostic component receives short string identifiers that may need palindrome validation. Write a function that determines whether a string reads the same from left to right and right to left.

Compare characters exactly as provided. The comparison is case-sensitive, and spaces, punctuation, and digits are treated as ordinary characters. Do not modify, filter, or normalize the input string.

Formal Specification

Implement is_palindrome(s), where:

  1. s is a Python string.
  2. Return True if s is a palindrome.
  3. Return False otherwise.
  4. An empty string and a one-character string are palindromes.

Constraints

  • 0 <= len(s) <= 10^5
  • s contains standard Python string characters
  • Comparison is case-sensitive
  • Spaces and punctuation are treated as ordinary characters
