Problem

At Notion, you need a utility function that checks whether a given string reads the same forward and backward. Write a function that returns True if the input string is a palindrome and False otherwise.

Formal Specification

Input: A string s
Output: A boolean value
- True if s is identical to its reverse
- False otherwise

A palindrome comparison in this problem is case-sensitive and includes all characters, including spaces, punctuation, and digits.

Constraints

0 <= len(s) <= 10^5
s consists of any valid string characters, including letters, digits, spaces, and punctuation
Comparison is case-sensitive
All characters must be considered exactly as given
