This time I will bring you a simple bubble and two-way bubble sort case. What are the precautions for using bubble sequence? , the following is a practical case, let’s take a look.
Bubble sorting example, two-way bubble sorting and a slightly improved visualization of two-way bubble sorting.
Bubble sorting example
var ls=[ 98,13,6,25,38,36,30,44,38,80,61,28,47,34,95,18,85,58,89,85,42,61,74,35,13,14,80,7,10,44,10,47,13,11,52,25,24,48,34,12,88,80,33,8,80,45,64,52,79,77 ]; for(var i=0;i<ls.length;i++){ for(var j=i+1;j<ls.length;j++){ if(ls[i]>ls[j]){ ls[i]=ls[i]+ls[j]; ls[j]=ls[i]-ls[j]; ls[i]=ls[i]-ls[j]; } } }
Two-way bubble sorting example
var ls=[ 6,13,98,25,38,36,30,44,38,80,61,28,47,34,95,18,85,58,89,85,42,61,74,35,13,14,80,7,10,44,10,47,13,11,52,25,24,48,34,12,88,80,33,8,80,45,64,52,79,77 ]; for(var i=0;i<ls.length;i++){ for(var j=i+1;j<ls.length-i;j++){ if(ls[lent-1-i]<ls[lent-j]){ ls[lent-1-i]=ls[lent-1-i]+ls[lent-j]; ls[lent-j]=ls[lent-1-i]-ls[lent-j]; ls[lent-1-i]=ls[lent-1-i]-ls[lent-j]; }//后面的比较 if(ls[i]>ls[j]){ ls[i]=ls[i]+ls[j]; ls[j]=ls[i]-ls[j]; ls[i]=ls[i]-ls[j]; }//前面的比较 } }
Two-way bubble sorting slightly improved example
var ls=[ 98,13,6,25,38,36,30,44,38,80,61,28,47,34,95,18,85,58,89,85,42,61,74,35,13,14,80,7,10,44,10,47,13,11,52,25,24,48,34,12,88,80,33,8,80,45,64,52,79,77 ]; var lent=ls.length; for(var i=0;i<ls.length;i++){ for(var j=i*2;j<ls.length-2*i;j++){ if(ls[i*2]>ls[j+1]){ ls[i*2]=ls[i*2]+ls[j+1]; ls[j+1]=ls[i*2]-ls[j+1]; ls[i*2]=ls[i*2]-ls[j+1]; }//保持内层第一个数为循环最小 if(ls[lent-i*2-1]<ls[lent-j-1]){ ls[lent-i*2-1]=ls[lent-i*2-1]+ls[lent-j-1]; ls[lent-j-1]=ls[lent-i*2-1]-ls[lent-j-1]; ls[lent-i*2-1]=ls[lent-i*2-1]-ls[lent-j-1]; }////保持内层倒数第一个数为循环最大 if(ls[lent-2-i*2]<ls[lent-j-1]){ ls[lent-2-i*2]=ls[lent-2-i*2]+ls[lent-j-1]; ls[lent-j-1]=ls[lent-2-i*2]-ls[lent-j-1]; ls[lent-2-i*2]=ls[lent-2-i*2]-ls[lent-j-1]; }//倒数上一个 if(ls[i*2+1]>ls[j+1]){ ls[i*2+1]=ls[i*2+1]+ls[j+1]; ls[j+1]=ls[i*2+1]-ls[j+1]; ls[i*2+1]=ls[i*2+1]-ls[j+1]; }//下一个 } }

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.
