I. Linked listWhen learning the list of data structures, there are linked lists that differentiate between the leading nodes and the nodes that do not take the lead .At that time, after writing the basic operation algorithm of the link list of the lead node, I wrote the basic operation of the linked list without the le

Linked lists are one of the simplest data structures, and when we use arrays to store data, frequent insertions and deletions can consume a lot of performance, and a linked list is a linear data structure that is suitable for frequently inserting and deleting operations.A detailed introduction to the linked

that is stored efficiently and then finds Will generate aggregation Separation Chain Method: Hash list is the combination of sequential storage and chained storage, and the storage efficiency and search efficiency of the linked list are low. Keyword deletion does not require the "lazy Delete" method, which does not store "garbage". Too small α may lead to space waste, large alpha will pay

The hash table is also one of the data structures supported by Redis, which uses both redis_encoding_ziplist (compressed list) and redis_encoding_ht (data Dictionary) encoding methods.When a hash table uses a compressed list, it uses the following structure to store the data

Introduction:A linked list is one of the important members of a data structure. Because of its simple structure, dynamic insertion, deletion of nodes, the advantages of less time, the list in the development of the application of many scenarios. Second only to arrays (the more simple the wider the application).But. As with its strengths, the drawbacks of the
