Review Summary
Great job on the overall implementation of the MyHashMap! The core logic for handling puts, gets, and resizing is well-executed. However, there are a couple of changes required to meet the project's coding standards.
First, the private static class Node should be moved to the end of the MyHashMap class, after all public methods. This is required by the project's style guide. [CHECKLIST ITEM #5]
Second, the resize() method uses the magic number 2 to double the capacity. Please extract this value into a named constant, such as CAPACITY_MULTIPLIER, to improve code clarity and maintainability. [CHECKLIST ITEM #2]
Once these adjustments are made, your solution will be ready for approval. Keep up the great work!

This violates checklist item #5: 'Private methods and classes should be after public ones in your class.'. The private inner class Node should be moved to the end of the MyHashMap class, after the getSize() method.

This violates checklist item #2: 'Any magic numbers should be constants'. The value 2 used for doubling the capacity should be extracted into a named constant, for instance, CAPACITY_MULTIPLIER, to improve readability and maintainability.

Review Summary
Excellent work addressing the previous feedback! You've correctly handled the magic numbers and the placement of the nested Node class. There is just one remaining style requirement to address. According to the project checklist, all private methods must be placed after all public methods [CHECKLIST ITEM #5]. Please move the resize() and getIndex() methods to after the getSize() method. Once you make this small adjustment, your solution will be perfect!

This violates checklist item #5: 'Private methods and classes should be after public ones in your class.' Please move this private method and getIndex() after all public methods (e.g., after getSize()).

Review Summary
Excellent work on your MyHashMap implementation! You've done a great job addressing the previous feedback by reordering the private methods, which has significantly improved the structure of your code. Your implementation is clean, correct, and demonstrates a solid understanding of how hash maps function. The logic for handling collisions and resizing is well-executed. I am happy to approve your solution. Keep up the fantastic work!
