Start building 1. Create project Let’s find a place to create a new directory, name it “my-test-toolkit”, and then use the terminal in the directory to run npm init -y to generate the project configuration file< strong>package.json. 2. Installation tools Then we will install Selenium and Nightwatch. Install selenium-standalone: npm install selenium-standalone –save-dev Install Nightwatch: […]

Clever use of Kotlin attribute delegation – point reporting encapsulation
Overview In actual project development, there will definitely be a need for reporting. The reporting method may be different for each project. Some are automated and do not require manual reporting by developers. Some require developers to report by themselves. In one of our business projects, because we adopted a business-driven iterative approach, there were […]

C language internal skill training—detailed explanation of pointers (beginner level)
Foreword: They say that it only takes a few weeks to speak a language. I disagree with this statement, at least not after I learned C language pointers. Do not believe? Come show your talents: //Code 1 (*(void (*)())0)(); //Code 2 void (*signal(int , void(*)(int)))(int); These two lines of code are from “C Pitfalls and […]

CodeForces 19D Points (discretization + segment tree + single point update)
Question link: huangjing Question meaning: three operations are given 1: add(x,y) adds this point to the two-dimensional coordinate system 2: remove(x,y) removes this point from the two-dimensional coordinate system. 3: find (x, y) is to find the first point on the upper right side of (x, y). Idea: We can establish n sets with x […]
