Backend Challenge - Palindrome Checker API

Introduction

The "Palindrome Checker API" challenge is designed to build a REST API that determines whether a given string is a palindrome.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement an endpoint (/check) for checking palindromes.
  • Understand HTTP methods (POST for sending data) and status codes.

Instructions

  1. Objective: Develop a REST API that checks whether a given string is a palindrome.

  2. Environment Setup: Choose your preferred programming language (e.g., JavaScript, Python, Java, C#) and set up the necessary environment.

  3. Implementation Details:

    • Define an endpoint (/check) that accepts a string via HTTP POST requests.
    • Implement logic to determine if the input string is a palindrome.
    • Return a response indicating whether the string is a palindrome (true/false) as JSON.

  4. Testing: Test your API using a HTTP client (e.g., Postman, curl).

    • Send POST requests to the /check endpoint with different strings.
    • Verify that the response correctly identifies whether each string is a palindrome and that status codes are appropriate (e.g., 200 OK).

Possible Improvements

  • Case Insensitivity: Make the palindrome check case-insensitive (e.g., "Racecar" should be considered a palindrome).
  • Whitespace Handling: Ignore whitespace characters during palindrome check.
  • Edge Cases: Handle edge cases such as empty strings or single-character strings.
  • Performance: Optimize the palindrome checking algorithm for efficiency, especially for longer strings.

Conclusion

By completing this challenge, you will gain practical experience in developing a Palindrome Checker API and learn essential practices for backend development. Explore additional improvements and challenges to further enhance your skills.

Happy coding!
