Linear structure1. A unique linear relationship is met between data elements.2. Each data element (except the first and last) has only one direct predecessor and one direct successor.Linear table (sequential table, linked list, stack, queue)1. The simplest and most common form of data structure2. A finite sequence consisting of n data elements (nodes)Sequential table1. The data elements of the linear table are stored in logical order in a set of true

-linked list is a kind of chain access structure, in order to find the first Data element, we must find the first i-1 data element. The shaded area in the figure represents the data field, and the white space represents the pointer field. And the last pointer field is empty.Circular link ListThe circular chain list is another form of chain-storage structure. Its

1. Introduction Start with this blog to introduce some basic data structure knowledge. This article and the next one will introduce several basic data structures: Stacks, queues, linked lists, and root trees. Methods for constructing objects and pointers from arrays are also described. This article mainly introduces stacks and queues, both of which ar

For example: (in order to be simple, using a small starting sort cardinality, in practical applications, should use a large starting base, and should take 2 of the integer power, such as 65536=2^16, the following said sort refers to ordernum from small to large sort).
