Course Introduction：In interviews, we are often asked what algorithms we know. In this course, PHP Chinese has recorded some common classic algorithms for you and explained their implementation principles in detail in the form of videos. I hope it can help the majority of PHP learners and interviewers.

Course Introduction：Compare two different transitive closure algorithms: Matrix Multiplication Algorithm vs Reflection Closure Algorithm The transitive closure algorithm is used to find the transitive closure of a relationship, that is, all transitive relations on the relationship. In computer science, there are many ways to implement the transitive closure algorithm. In this article, we will compare two common transitive closure algorithms: the matrix multiplication algorithm and the reflective closure algorithm. We will introduce the principles and code examples of each algorithm in detail, and compare them by performance and applicable scenarios. Matrix multiplication algorithm: The matrix multiplication algorithm is an efficient transitive closure

Course Introduction：Binary arithmetic is an operation method based on binary numbers. Its basic operations include addition, subtraction, multiplication and division. In addition to basic operations, binary arithmetic also includes logical operations, displacement operations and other operations. Logical operations include AND, OR, NOT and other operations, and displacement operations include left shift and right shift operations. These operations have corresponding rules and operand requirements.

Course Introduction：Comparison of transitive closure algorithms: bottom-up algorithm vs top-down algorithm Introduction: The transitive closure algorithm is a commonly used algorithm in graph theory, which can find the transitive closure of a graph in a directed or undirected graph. In this article, we will compare two common implementation methods of the transitive closure algorithm: bottom-up algorithm and top-down algorithm, and give specific code examples. 1. Bottom-up algorithm: The bottom-up algorithm is an implementation method of the transitive closure algorithm. It constructs the transitive closure of the graph by calculating all possible paths in the graph. Its algorithm steps
