Least Frequently Used (LFU) Cache

In this video, we will learn how to implement the Least Frequently Used (LFU) Cache. LFU Cache is a caching algorithm that removes the least frequently accessed cache block when the cache reaches its capacity. We will explore various approaches to implement LFU cache, including using arrays, singly linked lists, doubly linked lists, and hashing techniques.

The video will explain how LFU Cache operates with functions like get(key) and put(key, value), which return values from the cache or add/update values, while ensuring that the least frequently used key-value pair is removed when the cache exceeds its capacity. Watch this video to understand the inner workings of LFU Cache and how to implement it efficiently with different methods and approaches.
