The least recently used (LRU) algorithm is one of the most famous cache replacement algorithms and for good reason! As the name suggests, LRU keeps the least recently used objects at the top and evicts objects that haven't been used in a while if the list reaches the maximum capacity. So it's simply an ordered list where objects are …
