What is the difference between sequential storage structure and chain storage structure?

The difference between the sequential storage structure and the chain storage structure is: 1. The memory addresses of the chain storage structure are not necessarily continuous, but the memory addresses of the sequential storage structure must be continuous; 2. Chain storage It is suitable for inserting, deleting, and updating elements more frequently, while the sequential storage structure is suitable for frequent queries.

The difference between sequential storage structure and chain storage structure

1. The memory address of chain storage structure is different. It must be continuous, but the memory address of the sequential storage structure must be continuous;

2. Chain storage is suitable for inserting, deleting, and updating elements more frequently, while the sequential storage structure is suitable for frequent queries. when used.

Advantages and disadvantages of sequential storage structure and chain storage structure:

In terms of space,

Sequential storage saves space than chain storage. This is because each node in the chain structure has a pointer storage domain.

Storage operations:

Sequential support for random access, convenient operation

Insertion and deletion:

Chained ones are more convenient than sequential ones ( Because the sequential table is also very convenient for insertion, the problem is that the insertion of the sequential table requires greater space complexity, including an index from the head of the table and the movement of the elements after the index, while the linked list is indexed and the insertion is completed)

For example: When you search for a letter j in the dictionary, you can choose two methods. First, search sequentially, starting from the first page until j is found. Second, index query, directly find out the page number of j from the dictionary index, and directly find the page number, which may be faster than sequential query.
