Course Introduction：The launch of Node.js not only automates more trivial and time-consuming work from an engineering perspective, but also breaks the language boundaries between front-end and back-end, allowing JavaScript to run smoothly on the server side. This series of courses is a series of courses, and the leading course is "Attack on the Basics of Node.js (1)", so it is recommended that friends take it before learning this course.

Course Introduction：Introduction: PHP provides powerful system functions to help us complete functions, but sometimes it is not enough to just use system functions. Custom functions need to be encapsulated according to the business, as explained in "PHP Advanced - Function Video Tutorial" It explains how to customize functions and common problems in custom functions. It is a must-read course for getting started with PHP.

Course Introduction：A function is a block of code that implements a specific function. The direct purpose of defining a function is to divide the program into blocks according to functions, so as to facilitate the use, management, reading and debugging of the program. Functions can be roughly divided into system functions and custom functions. When the functions provided to us in the system cannot achieve a specific function you want to achieve, you need to define a function yourself. This is called a custom function. , of course there are some special forms of functions in PHP, such as recursive functions, callback functions, etc.

Course Introduction：The binary representation of negative numbers usually uses two's complement notation. The steps are: 1. Convert the negative number into the binary representation of its corresponding absolute value. For example, the absolute value of -5 is 5, and its binary representation is 101; 2. Convert this binary number to its complement. The complement number is calculated by inverting the binary representation of the corresponding positive number (0 becomes 1, 1 becomes 0), and then adds 1. For the above example, after inverting, we get 010, and adding 1 to get 011; 3. The binary number obtained is the complement representation of the negative number. Therefore, the two's complement representation of -5 is 011.

Course Introduction：Detailed explanation of binary functions in C++ Binary functions are an important type of functions in computer science. They are based on binary operations and are used to process binary data. In C++, binary functions provide rich functions that can perform bit operations, displacement operations, and logical operations. 1. Bit operation Bit operation is a method of operating on each bit of binary data. C++ provides a variety of bit operation functions, including bitwise AND (&), bitwise OR (|), bitwise XOR (^), bitwise negation (~), etc. Bitwise AND (&) Bitwise AND operation is used for

Course Introduction：FibbinaryNumbers are numbers that do not have consecutive 1's in their binary representation. However, they can have consecutive zeros in their binary representation. Binary representation is a representation that displays numbers using base 2, with only two digits 1 and 0. Here we will be given a number and need to determine if the given number is a fibbinary number. Input1:Givennumber:10Output:Yes Explanation - The binary representation of the given number 10 is 1010, which indicates that there are no consecutive 1's in the binary form. Input2:Givennumber:12Output:No Explanation − The binary representation of the given number is 1100, which indicates the binary form
