singly linked list implementation in java

left sub-leaf node of the current element.2. The next element of the doubly linked list constructed by the current node is the smallest node of the right child node of the current node, see 1.3. The previous element of the doubly linked list constructed by the current node is the node of the last operation.The code is as follows:public class Bstreenode {private Integer value;private bstreenode leftnode;pri

last node to the header node instead of being NULL as a single-linked table. In this case, a new node is inserted after the last node. 2. When determining whether the end of the table is reached, it is to determine whether the value of the node chain domain is the header node. When the Chain Domain value is equal to the header pointer, it indicates that it has reached the end of the table. Instead of determining whether the Chain Domain value is NULL like a single-chain table.

In the development process, the encounter to generate a list object, you need to check every object inside it. However, this list sometimes has duplicate data. Therefore, it is necessary to go heavy to avoid duplicate checksums. 1. Writing without type: List listwithoutdup = new ArrayList (new HashSet (Listwithdup)); 2. With type (for example, Strin

This example for you to share the News list page query Java code for your reference, the specific content as follows Package com.ibeifeng.test; Create a news test class public class Newtest {private long id; private string title; private string content; private string author; Public Newtest () {super ();} Public newtest (long ID, string title, string content, string author) {this.id = ID; Thi

On the previous blog, Web version RSS reader (i)--dom4j read XML (OPML) file has said how to read the RSS subscription file. This time read the subscribed files to the page and use the tree structure to load the display. Do not intend to use a special control for the tree display, do not want to write their own, want to jingxiang some, just in A JS tree script--dtree was found on the Internet. Dtree is an easy to use JavaScript tree The Menu control. Supports infinite ratings, you can place m

This paper mainly introduces two methods of single-linked list inversion, which are recorded as follows:1.Package Com.leetcode;public class Listreverse {public static void main (string[] args) {node Node1 = new Node (1); Node Node2 = new node (2); Node Node3 = new node (3); Node Node4 = new node (4); node1.next = Node2;node2.next = Node3;node3.next = Node4; Node head = reverse (Node1); while (head! = null) {System.out.println (head.val); head = Head.n

From Java data structure and algorithm book If the node is inserted, current points to the inserted element, and if the node is deleted, then current=current.next; Here's the complete code: Package com.xll; public class Interiterapp {public static void main (string[] args) {singlelinklist singlelinklist = new Singlelink List (); Iteratorlist iteratorlist = Singlelinklist.getiteratorlist (); Iterato
