What is the condition that the single linked list head of the leading node is empty? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The condition that the single linked list head of the leading node is empty is: [head- > next==head]. A single linked list is a linked data structure in which a set of storage units with arbitrary addresses are used to store the data elements in the linear table. The data in the linked list is represented by nodes, each of which is composed of elements and pointers.

The condition that the single linked list head of the leading node is empty is: head- > next==head.

Single linked list

A single linked list is a linked data structure in which a set of storage units with arbitrary addresses are used to store the data elements in the linear table.

The data in the linked list is represented by nodes, the composition of each node: element (the image of the data element) + pointer (indicating the storage location of the subsequent element), the element is the storage unit for storing data, and the pointer is the address data connected to each node.

Node structure

Data domain-the data field where node values are stored

Next domain-the pointer domain (link domain) that stores the directly following address (location) of the node

The linked list links the n nodes of the linear list according to its logical order through the link domain of each node, and the linked list with only one link domain of each node is called a single linked list.

Header pointer head and terminal node

The storage address of each node in the single linked list is stored in its frontal node next domain, and the start node has no precedent, so the header pointer head should be set to point to the start node. The linked list is uniquely determined by the header pointer, and the single linked list can be named after the header pointer.

The terminal node has no successor, so the pointer domain of the terminal node is empty, that is, NULL.

The answer to the question about what is the empty single linked list head of the leading node is shared here. I hope the above content can be of some help to everyone. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
