How do I implement LRU caching in my application?
An example of an AI chatbot conversation about implementing LRU caching in applications.
How do I implement LRU caching in my application?
To implement LRU (Least Recently Used) caching, you can use a combination of a hash map and a doubly linked list.
Can you explain how the hash map and linked list work together?
Sure! The hash map stores the keys and pointers to the nodes in the linked list, while the linked list maintains the order of usage.
What happens when the cache reaches its limit?
When the cache reaches its limit, you remove the least recently used item from the linked list and the hash map.
Are there any libraries that can help with this?
Yes, many programming languages have libraries for LRU caching, like functools.lru_cache in Python.
