Linked List or Palindrome Coding | Dataford Interview Questions

Catalina promotion systems can use short tokens whose characters must read identically from both directions. Given a token, determine whether it is a palindrome.

A string is a palindrome if it reads the same left to right and right to left. The comparison is case-sensitive, and every character is significant.

Formal Specification

Implement is_palindrome(s), which accepts a string s and returns a boolean:

Return True if s is a palindrome.
Return False otherwise.

Constraints

0 <= len(s) <= 10^5
s contains printable ASCII characters
The comparison is case-sensitive
Do not create a reversed copy of the string

Function Signature

def is_palindrome(s):
