Review Summary

Great job on implementing the core functionality of the Dictionary class! The overall structure is solid. However, a couple of changes are needed to fully meet the project requirements.

First, the task description specifies that each node should store the key, hash, and value. Your current implementation in app/main.py only stores the key and value. Please update your node structure to include the pre-calculated hash.

Additionally, the KeyError you raise in __getitem__ is missing a descriptive message, which is a checklist requirement. It's important to provide context for the error, for example: raise KeyError(f"Key not found: {key}").

Once these two points are addressed, your solution will be fully compliant. Keep up the great work!

Review Summary

Great job addressing the previous feedback! Your Dictionary class is well-implemented and meets all the requirements, so I am approving your submission. The logic for handling nodes, including storing the hash and providing descriptive error messages, is solid.

As a small suggestion for future improvement, in your _resize method, you recalculate the hash of the key to find its new index. Since you already have the hash stored in the node, you can make this more efficient by using the stored value directly. This is a minor optimization, and your current code works perfectly. Keep up the fantastic work!

You're recalculating the hash of the key here, but the hash_key is already available from the node you're processing. Consider using the stored hash to determine the new_index to make this more efficient and align with the purpose of storing the hash in the first place.
