Witryna13 paź 2024 · LRU Cache. Design and implement a data structure for Least Recently Used (LRU) cache. It should support the following operations: get and put. get (key) - Get the value (will always be positive) of the key if the key exists in the cache, otherwise return -1. put (key, value) - Set or insert the value if the key is not already present. WitrynaDesign and implement a data structure for Least Recently Used (LRU) cache, which supports get and put. Analysis. The key to solve this problem is using a double linked list which enables us to quickly move nodes. The LRU cache is a hash table of keys and double linked nodes. The hash table makes the time of get() to be O(1).
