WebLeast Recently Used (LRU) algorithm is a page replacement technique used for memory management. In this method, the page which is least recently used is repl... WebThe least frequently used (LFU) is a cache algorithm used to manage memory within a computer. In this method, the system keeps track of the number of times a block is referenced in memory, and when the cache is full, our system removes the item with the lowest reference frequency. LFU cache get and put operation works in O(1) average …
