This article uses .c files to call functions, and .h files to define the layout of functional functions. Because no other space is occupied when doing merge and intersection difference, after executing a function, the values of the two linked lists have changed and are no longer the original values, so after each function is […]

Use the Intersection Observer API to detect whether an element appears in the visual window
Use the Intersection Observer API to detect whether an element appears in the visual window API interpretation: The Intersection Observer API provides a method to asynchronously detect changes in the intersection of a target element and its ancestor element or viewport (collectively referred to as the root element). Note: Because this API is asynchronous, it […]
Calculate the intersection of two straight lines given four point coordinates
Article directory 1 chatgpt4 2. A word of Wen Xin 3. Spark 4. Bard Summarize I used Chatgpt4, Wen Xinyiyan, iFlytek Spark, and Google Bard to search for this question and gave the answers respectively. Let me talk about the conclusion first. Chatgpt4 and Wen Xinyiyan gave the correct answer, and the other two parts […]
Topological sorting analysis: the intersection of computers and mathematics and C++ implementation
1. Introduction (Introduction) Topological sorting is a concept often mentioned in the fields of computer science and mathematics. But why is it so important? Why do we need to understand it? In this chapter, we will delve into the definition, background, and real-life applications of topological sorting. 1.1 The definition and background of topological sorting […]
Insert at the end of a singly linked list, find the middle node of a singly linked list, delete specified elements of a singly linked list, invert a singly linked list, find the Kth node from the bottom of a singly linked list, detect whether a singly linked list is a palindrome structure, find the intersection point of two singly linked lists, and judge a singly linked list. Whether the linked list has a ring and whether the singly linked list is destroyed
//Singly linked list node definition, tail insertion and output #include<iostream> #include<malloc.h> #include<assert.h> using namespace std; typedef struct listNode { struct listNode* next; int data; }node; //Divided into two situations, the linked list is empty and the linked list is not empty void lastInsert(node** list,int da) { node* n = (node*)malloc(sizeof(node)); n->data = da; n->next = […]
Implement intersection, union, and difference operations of sets based on two-way circular linked lists
1. This code can be run directly, but some special symbols such as ? may become ? , you can modify it yourself 2. Experimental objectives: Through this experiment, students can review and consolidate the loop structure, loop control conditions, branch structures, arrays/linked lists, function calls and other related contents in C language, and realize […]
Using C++ to realize rear intersection of single-chip space
Overall process The specific flow chart of code implementation is as follows: Data processing and class object creation The data provided is as follows: The four control points and image points are as shown in the figure, the focal length f = 153.24 mm, and the scale bar m = 50000. During the programming process, […]
Stream flow: Examples of intersection, difference set, collection of a certain field, and sorting
Some common operations on stream Intersection Difference set Get a certain field of the collection Set sorting PS: If you don’t like to read concepts, you can go directly to the source code examples. anyMatch (intersection) Determine whether any element in the data list meets the set predicate condition. If so, return true, otherwise return […]
Linux shell calculates the union, intersection, and difference of two files
Suppose we now have two files a.txt and b.txt The content in a.txt is as follows: a c 1 3 d 4 The content in b.txt is as follows: a b e 2 1 5 #Example 01 Compute the union: [root@VM_81_181_centos ~]# sort -u a.txt b.txt 1 2 3 4 5 a b c d […]
Calculate the intersections and intersection sequence of the route planning route
1. Algorithm background At present, many projects require the ability to plan routes. There are many open source map SDKs or paid SDKs that can achieve this. The user selects the starting point, end point and route points to plan the route the user wants, but the ability to identify intersections is average. It is […]
