Problem

At Grammarly, 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 when reversed
- False otherwise

A palindrome comparison in this problem is case-sensitive and includes all characters exactly as they appear.

Constraints

s may contain letters, digits, spaces, or symbols
Comparison is case-sensitive
All characters are compared exactly as given
