“Data Structure, Algorithm and Application C++ Language Description” – Code to implement key-value ordered linked list jump list

Skip list Definition Searching in a dictionary of n number pairs described by an ordered linked list requires at most n key comparisons. If a pointer is added to the middle node of the linked list, the number of comparisons can be reduced to n/2 + 1. At this time, in order to find a […]

[Data structure] Sequence table | Detailed explanation

There are two basic storage structures used to store linear tables in computers: sequential storage structures and chained storage structures. This article introduces the use of sequential storage structure to realize linear table storage. Sequential storage definition The sequential storage structure of a linear list refers to a storage unit with consecutive addresses that stores […]
