When should I use LRU or MRU caching strategies?

Can you explain when to use LRU or MRU caching strategies?

Sure! LRU (Least Recently Used) is best when you want to keep frequently accessed items, while MRU (Most Recently Used) is useful when older items are less likely to be reused.

What are the advantages of using LRU over MRU?

LRU is generally more effective in scenarios where access patterns are unpredictable, as it retains items that are used more often.

Are there any specific use cases for MRU?

Yes, MRU can be beneficial in situations like caching web pages where the most recently accessed pages are likely to be accessed again soon.

How do I implement LRU or MRU in my application?

You can implement LRU using data structures like a hash map combined with a doubly linked list, while MRU can be implemented similarly but with a different eviction policy.
