The two-way leading circular linked list is the most complex one in structure, but it also brings advantages that other linked lists do not have because of its complex structure. Today we will introduce the two-way leading circular linked list and complete its construction. 1. What is a two-way cycle linked list? 1.1 one way non leading non c ...

3.1 definition of linear table Definition: a finite sequence of zero or more data elements The first element has no predecessor and the last element has no successor The number of linear table elements n (n > = 0) is defined as the length of the linear table. When n=0, it is an empty table Permutations must be of the same data type In ...

bug log post The title requirements are as follows: Main class: in the main method, the constructStudentList method is called to construct a Worker object list, and the computeAverageScore method is used to calculate the average score of a class and output it to the screen. Write Student class and StudentList class as required. The programmin ...

        Continued Red black tree, insertion and deletion, better understanding , in this article, I won't introduce the understanding part too much, because what I said in the last article is almost the same. Next, I will implement the red black tree based on C + +. Similarly, you are welcome to ask questions ...

Because the interview big factory was hanged, I finally made up my mind to make up for it jdk1.7 is a segment lock implementation of segment lock, and 1.8 does not have segment lock Let's talk about the process of putValue: Throw a null pointer if the key is not empty Get table array Judge whether the table is empty. If it is empty, expan ...

Cough, I'm Xiaobai. Yes, the main plot is back again. Now I'm in trouble. My boss asked me to design a class that can be used to save the data of multiple customers. Can step 1 be implemented only with Java classes? With my current Java skills, I only know that I can create a new Java class, and then write properties and methods in the Ja ...

04 - sequence table and stack exercise Title Description Zuma is a game once popular all over the world. Its playing method is: several colored beads are initially arranged on a track, of which any three adjacent beads will not be completely the same color. After that, you can launch the beads into orbit and add them to the original sequenc ...

1. Concept of linked list Linked list is a basic data structure. Linked list can dynamically allocate storage. In other words, linked list is a very powerful array. It can define a variety of data types in nodes, and can add, delete and insert nodes as needed. We only allocate memory for one node at a time. The linked list uses pointers to ...

Preorder traversal and postorder traversal First traverse the root node, then the left subtree, and then the right subtree. Post order traversal first traverses the left subtree, then the right subtree, and then the root node. Recursive implementation of preorder traversal: public static void preOrderByRecursion(TreeNode root) { // Prin ...
