C + + different cache implementations (timeout clearing, least frequent use of LFU, LRU)
This paper mainly implements different cache s because there is a similar problem to be implemented in the previous written test, and there are similar training problems on Niuke, so this paper makes a summary;map is used as the key value storage in the cache, which is the fastest when queryinUTF-8...
