...做到get和put都是O(1)。因为还有put函数，要可以remove least recently used cache，所以还需要一个数据结构来记录顺序，自然想到list。set以及delete操作在LinkedList里面都是O(1)，就是要找到已存在的key这个操作在list是O(N)，因为即要删除leas...
...使用频率，我会把使用最少的缓存替换出缓存区。 Least Recently Used (LRU) 我会把最近最少使用的缓存数据踢走。 浏览器就是使用了我（LRU）作为缓存算法。新的对象会被放在缓存的顶部，当缓存达到了容量极限，我会把底部的对...
LRU 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 rece...

...因此 LRU 缓存淘汰算法就出现了。LRU 原理与实现LRU (Least Recently Used) 缓存淘汰算法提出最近被频繁访问的数据应具备更高的留存，淘汰那些不常被访问的数据，即最近使用的数据很大概率将会再次被使用，抛弃最长时间未被访问...
