What are some tips for implementing LRU caching?
When implementing LRU caching, consider using a combination of a hash map and a doubly linked list for efficient access.
Can you explain how the hash map and doubly linked list work together?
Sure! The hash map allows for O(1) access to cache items, while the doubly linked list maintains the order of usage for LRU eviction.
What are some common pitfalls to avoid during implementation?
Common pitfalls include not handling cache size limits properly and failing to update the usage order correctly.
Any specific libraries or frameworks you recommend for LRU caching?
Yes, libraries like Guava for Java or the lru_cache
decorator in Python's functools
module are great options.
