What are the differences between LRU and MRU cache algorithms?

What are the differences between LRU and MRU cache algorithms?

LRU (Least Recently Used) evicts the least recently accessed items, while MRU (Most Recently Used) evicts the most recently accessed.

In what scenarios would you prefer LRU over MRU?

LRU is preferred in scenarios where older data is less likely to be reused, like web caching.

Can you give an example of when MRU would be more effective?

MRU is effective in situations where the most recently accessed data is less likely to be needed again soon, like in certain database queries.

How do these algorithms impact performance?

LRU generally provides better performance for workloads with temporal locality, while MRU can be faster in specific use cases.
