#Caching

Design a caching solution using Redis based on fundamental data structure concepts. Explain the components of the system and how data would be managed within the cache.

Implement a Least Recently Used (LRU) Cache. Consider the appropriate data structures for implementation. You will also need to provide a verbal explanation of your approach and write pseudocode before converting the pseudocode into working code and executing it.

Create a memoization function that caches its output based on the input arguments. Each cached entry should have an expiration time to ensure irrelevant values are removed over time.

How do you ensure that every user has access to the updated website content after a new production deployment by clearing the cache?
