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

  • 0 <= len(s) <= 10^5
  • s may contain letters, digits, spaces, or symbols
  • Comparison is case-sensitive
  • All characters are compared exactly as given
