How do LRU and MRU caching algorithms differ?

Can you explain the differences between LRU and MRU caching algorithms?

Sure! LRU stands for Least Recently Used, while MRU stands for Most Recently Used. LRU evicts the least recently accessed items, whereas MRU evicts the most recently accessed items.

What are the advantages of using LRU over MRU?

LRU is generally more effective in scenarios where older data is less likely to be reused, making it suitable for many applications.

Are there specific use cases where MRU is preferred?

Yes, MRU can be beneficial in situations where the most recently used items are less likely to be needed again soon, like in certain database caching scenarios.

How do these algorithms impact performance?

The choice between LRU and MRU can significantly affect cache hit rates and overall system performance, depending on the access patterns of the data.
