In-Memory Cache System Implementation

I've implemented an in-memory cache system designed to support various eviction policies and data types, with a fresh perspective on design patterns and SOLID principles. Additionally, I've included unit test cases to ensure reliability.

Key Features:

• Comprehensive Cache: Offers a unified Cache interface accommodating different cache implementations like LRUCache and LFUCache, supporting various eviction policies.
• Strategy Pattern: Eviction policies are implemented separately, allowing seamless switching between LRU and LFU strategies without code redundancy.
• Decorator Pattern: The CacheDecorator class enhances functionality, such as logging or metric reporting, for any cache implementation without altering its core logic, promoting code reusability.
• DRY Principle: Avoids code duplication by employing the Decorator pattern to add behavior before the get() operation, ensuring maintainability.
• Enhanced Extendability: The CacheFactory class simplifies the creation of decorated cache instances, facilitating the addition of new cache implementations or decorators without modifying existing code.
