Article Introduction：How to implement topological sorting algorithm using Python? Topological sorting is a sorting algorithm in graph theory used to sort directed acyclic graphs (DAG). In topological sorting, nodes in the graph represent tasks or events, and directed edges represent dependencies between tasks or events. In the sorted result, all dependencies are satisfied and each node is ranked after all its predecessor nodes. Implementing the topological sorting algorithm in Python can be solved using the idea of ​​depth-first search (DFS). Here is a specific code example: f

Article Introduction：How to use Java to implement topological sorting algorithm Topological sorting is a commonly used algorithm in graph theory, used to sort the vertices of a Directed Acyclic Graph (DAG for short). Topological sorting can be used to solve problems such as dependencies or task scheduling. In this article, we will introduce how to use Java to implement the topological sorting algorithm and give corresponding code examples. The implementation idea of ​​topological sorting is as follows: First, we need to define a data structure of a directed graph, which can be done using an adjacency list.

Article Introduction：PHP algorithm design ideas: How to achieve an efficient solution to the topological sorting problem? Topological sorting is a classic problem in graph theory. Its main goal is to sort a directed acyclic graph (DAG) so that all vertices in the graph satisfy the condition that the in-degree is less than or equal to the out-degree. Topological sorting is widely used in many scenarios, such as task scheduling, compiler design, etc. In this article, an efficient solution for topological sorting using PHP language will be introduced. First, we will discuss the basic principles of topological sorting algorithm, and then give specific codes.

Article Introduction：Paving the way for directed graphs: The algorithm we are going to talk about in this section involves directed graphs, so I will first explain some concepts of directed graphs and will not explain them later in the article. First, the nodes of the directed graph are connected by lines with arrows. Nodes have the concepts of out-degree and in-degree. The out-degree of the node pointed by the tail of the connection is increased by 1, and the in-degree of the node pointed by the arrow at the head of the connection is increased by 1. Look at the following example, A has an in-degree of 0 and an out-degree of 2, B has an in-degree of 1 and an out-degree of 1, C has an in-degree of 1 and an out-degree of 1, D has an in-degree of 2 and an out-degree is 0. Adjacency list: The adjacency list is an effective way to store the graph structure. As shown in the figure below, the node array on the left stores all the nodes in the graph, and the adjacency list on the right stores the adjacent nodes of the node. Introduction In this article we are going to talk about topological sorting

Article Introduction：Quick sort is a commonly used sorting algorithm with a time complexity of O(nlogn). In practical applications, quick sort is usually much faster than other sorting algorithms. Python provides many built-in sorting functions, but it is still important to understand and implement quicksort. In this article, we will implement the quick sort algorithm through Python. The working principle of quick sort is to select a pivot value (pivot), then put all elements in the list that are less than the pivot value in a sublist, and put all elements that are greater than the pivot value
