Data structure is a collection of data elements with structural characteristics. It studies the logical structure of data, the physical structure of data and the relationship between them. It defines the corresponding operation for this structure, designs the corresponding algorithm, and ensures that the new structure obtained after these operations still retains the original structure type. In short, data structure is a collection of data elements with one or more specific relationships, that is, a collection of data elements with "structure". "Structure" refers to the relationship between data elements, which is divided into logical structure and storage structure.
