C++ least recently used cache

WebSep 10, 2024 · LRU (Least Recently Used) Cache discards the least recently used items first. This algorithm requires keeping track of what was used when, which is expensive if one wants to make sure the algorithm always discards the least recently used item. WebLeast Recently Used (LRU) is a common caching strategy. It defines the policy to evict elements from the cache to make room for new elements when the cache is full, meaning it discards the least recently used items first. Let’s take an example of a cache that has a capacity of 4 elements. We cache elements 1, 2, 3 and 4.
