A linked list is a non-sequential, non-sequential storage structure on a physical storage unit, and the logical order of the data elements is achieved through the order of the pointers in the linked list. A linked list consists of a series of nodes (each element in the list is called a node) that can be dynamically generated at run time. Each node consists of two parts: one is the data field that stores the data element, and the other is the pointer field that stores the next node address. The operation is complex compared to the linear table order structure. Since they do not have to be stored sequentially, the list can achieve an O (1) complexity at the time of insertion, much faster than another linear table-order table, but the time to find a node or to access a particular numbered node requires O (n), while the corresponding time complexity of the linear and sequential tables is O (Logn) and O (1) respectively. Using the list structure can overcome the shortcoming that the array list needs to know the data size beforehand, the list structure can make full use of the computer memory space and realize the flexible memory dynamic management. However, the list loses the advantage of random array reading, and the spatial overhead of the linked list is larger due to the increase of the point-of-view pointer domain. The most obvious benefit of a linked list is that the regular array arranges the associated items in a different way than the data items are in the order of memory or disk, and the data accesses tend to be converted in different permutations. Lists allow you to insert and remove nodes from any location on the table, but do not allow random access. There are a number of different types of linked lists: one-way lists, two-way lists, and circular lists. Linked lists can be implemented in a variety of programming languages. The built-in data types of languages like Lisp and scheme include the access and operation of the linked list. Programming languages or object-oriented languages such as c,c++ and Java rely on variable tools to generate linked lists.
