If you don't say much, let's start with the renderings: The applet realizes the multi selection function of Treeview tree Realization idea Source data structure First, our data structure is roughly: [ { "id": "0", "name": "classification of animals", "pid": "-1", "children": [ { "id" ...

What is a graph In the previous article, we learned the concept of tree, focusing on binary tree. Graph is a little similar to tree in topology, but graph is not a tree Intuitively, let's first look at the topology of a graph: Undirected graph The above shows an undirected graph. An undirected graph is a graph without direction. As long a ...

Title Link Meaning: You have a length of n n The arrangement of n for a pair of subscripts i , j ( i < ...

1, Principle of cued binary tree Introduced earlier Binary tree The article mentioned that the binary tree can use two storage structures: sequential storage and chain storage. When using chain storage, there will be a large number of empty finger needle fields. In order to make full use of these empty finger needle fields, a cued binary t ...

Summary of ranking methods (stability and complexity issues) preface Data structure final exam, to analyze various sorting methods, complexity problems and stability problems, let's summarize here. I hope it can help you who are reading this article! ( ^ - ^ )! stability Generally speaking, the so-called stability is that if there are t ...

Critical path: Planning, construction process, production process and procedure process are usually regarded as a project. The project is usually divided into several sub projects called "activities". After these "activities" are completed, the project can be completed. AOE net is usually used to represent engineering. AOE ...

Bubble sorting algorithm O(N*N) of sorting algorithm: Principle: 1. Compare the size relationship of two adjacent elements from beginning to end for each element that is not sorted 2. If the element on the left is large, the two elements exchange positions 3. Move one position to the right and compare the following two elements 4. Moving to th ...

1. Hash table (hash) - Google computer questions Let's take a look at the actual demand. A computer question from google:In a company, when a new employee comes to report, it is required to add the employee's information (id, gender, age, address...). When entering the employee's id, it is required to find all the information of the employeeRe ...

Find program 2 in the comments (insert several nodes in the FRONT of the list). Modify The program inserts only three (3) nodes in front of the list. Test procedure. Q1 solution: Classes and functions remain unchanged. This is one of the main reasons for using functions, That is, we can change one function (or main function) while leaving eve ...

After adjusting the trees for a long time, they finally became gorgeous Main idea of the title: Given a tree structure, point 1 is the root of the tree The closer to the tree root, the higher the temperature. The existing survival temperature is in the [L,R] range. The virus appears at point X. if the temperature of a node is in the [L,R] range ...
