In this video, we tackle the "LRU Cache" design problem, a common coding interview question on implementing a Least Recently Used (LRU) Cache. The LRU cache requires managing key-value pairs with a constraint on capacity and evicting the least recently accessed item. To achieve O(1) time complexity for get and put operations, we will use a HashMap and a Doubly Linked List.
