WitrynaDesign and implement a data structure for Least Recently Used (LRU) cache. It should support the following operations: get and set. get(key) - Get the value (will always be positive) of the key if the key exists in the cache, otherwise return -1. set(key, value) - Set or insert the value if the key is not already present. WitrynaIntroduction. An operating system is responsible for running more than one process at a time. That’s why it needs to manage the memory efficiently. There are various ways like FIFO, LIFO, and LRU to accomplish this. A Least Recently Used (LRU) is a widely used technique. It arranges data in order of use, making it easy to see which ones haven't …
