Problem

In & General Intuition's mobile surfaces, lightweight input validation may need to detect whether a text string reads the same forward and backward. Write a function that returns whether a given string is a palindrome.

A palindrome is a string that is identical when reversed. For this problem, compare characters exactly as they appear: case, spaces, punctuation, and digits all matter.

Formal Specification

Input: a string s
Output: a boolean value
- True if s is a palindrome
- False otherwise

Constraints

0 <= len(s) <= 10^5
s may contain letters, digits, spaces, and punctuation
Comparison is case-sensitive
Do not remove or ignore any characters

Function Signature
