Palindrome String Program | Dataford Interview Questions

Creative Synergies Group uses short asset labels in review workflows. Implement a function that determines whether a label is a palindrome.

A palindrome reads the same from left to right and right to left. Compare characters exactly as provided: comparisons are case-sensitive, and spaces or punctuation are treated as ordinary characters.

Formal Specification

Implement is_palindrome(text).

Input: text, a string.
Output: Return true if text is a palindrome, otherwise return false.

Use a two-pointer approach that compares the first and last remaining characters, then moves inward. Return as soon as a mismatch is found.

Constraints

0 <= len(text) <= 100,000
text contains letters, digits, spaces, and punctuation
Character comparison is case-sensitive
Spaces and punctuation must be compared as ordinary characters

Function Signature
