Overview

XUrl is a utility that can be used to generate and retrieve short URLs when we don’t want to use the original longer URLs.

During the course of this project:

• Created a short url library with required methods.
• Implemented register method to take a long URL and return a shorter URL.
• Implemented a method to lookup the long URL by providing the short URL.
• Implemented hit count to track number of long URL lookups.
• Tested this implementation with test cases.

Scope of Work

• Concrete Class Implementation: Implemented a concrete class that provides methods for creating long URL to short URL mappings.
• Random Short URL Generation: Created a method to generate a random 9-character short URL for a given long URL and maintained this mapping using a hash map for quick retrieval.
• Custom Short URL Registration: Implemented a method to register a custom short URL for a given long URL.
• Error Handling: Ensured that each long URL maps to only one short URL and vice versa.
• Lookup Method Implementation: Created a method to lookup short URL for a given long URL from the mapping.
• Mapping Deletion: Implemented a method to delete mappings based on long URLs.
• Hit Count Implementation: Added a counter to keep track of the hit count for each long URL, indicating how many times a particular long URL has been looked up.
• Testing: Rigorously tested these methods using test cases.
