LRU Cache - System Design | How LRU works
In this video, we're going to reveal about LRU used in System Design: Typically LRU cache is implemented using a doubly linked list and a hash map. Doubly Linked List is used to store list of pages with most recently used page at the start of the list. So, as more pages are added to the list, least recently used pages are moved to the end of ...
