Did you come across this question in an interview?

  • If you had to store a lot of data and needed to keep track of recently used items, what data structure would you use?
  • Have you ever implemented a cache in your code? What kind did you use and why?
  • When optimizing your code's performance, what kind of cache might you use to reduce memory access time?
  • How would you make sure that the most recently used items in a large dataset are readily available to your program?
  • What do you know about Least Recently Used (LRU) caches?
  • Can you explain why an LRU cache might be useful in a program?
  • If you were building a system that needed to manage a large amount of frequently accessed data, would you consider implementing an LRU cache? Why or why not?
  • How would you design an LRU cache to ensure that it efficiently stores and retrieves the most recently used items?
  • In your experience, have you found that using an LRU cache improves performance? How so?
  • Can you describe a specific scenario where using an LRU cache would be particularly valuable?
  • Can you explain what the LRU cache is and its use case?
