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:ECMAScript 6 has basically become the industry standard. Mainstream front-end frameworks such as ReactJS, Vue.js, and angularjs will all use the new features of ES6. Its popularity is much faster than that of ES5. This chapter explains in detail the commonly used new features of ES6: different variable declarations, template strings, arrow functions, object and array destructuring, classes in ES6, and Module modular programming.

Course Introduction:否,Dijkstra 算法不是贪心算法。贪心算法在每个步骤中做出局部最优选择,希望最终得到全局最优解,而 Dijkstra 算法使用动态规划,通过考虑所有可能的子路径选择最短路径。其他贪心算法示例包括 Kruskal 算法、Prim 算法、哈夫曼编码、背包问题和贪婪着色算法。

Course Introduction:贪婪算法的目标是找到全局最优解,而贪心算法的目标是找到局部最优解。贪婪算法在每个步骤中选择全局最优解,而贪心算法选择局部最优解。两者都易于实现且时间复杂度低,但贪婪算法适用于优化问题,而贪心算法适用于更广泛的问题类型。

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.
