that of the kosaraju algorithm. In addition, the Tarjan algorithm is closely related to the Tarjan Algorithm for Finding undirected graph's dual-connected components (cut points and bridges. Learning the Tarjan algorithm also helps you to deeply understand the Tarjan Algorithm for dual-connected components. The two can be compared and combined. The Tarjan algorithm used to calculate the strongly connected component of a directed graph is named after its inventor

changing requirements, because some implementations have been completed and can be easily modified. This is the famous "language framework" model described by Robert and Johnson [96. A framework can reduce the cost of developing an application by an order of magnitude, but it is very difficult to use only one framework. A Framework defines a product with a typical architecture (such as an application or subsystem) that can be refined and specia

. Therefore, we need to separate the business process from the presentation layer and service. If it appears in a single program, the Smalltalk language is called mode-View-controller for such separation. It is worth noting that so many technologies are similarly associated with SOA. This is because SOA is not a specific technology, but a methodology that decouples optimized business functions from a variable process and presentation. This is the MVC of enterprise software.

programming. It is very beneficial to learn the basic software engineering principles in the future. Write 1A mess of programs is not as good as nothing to write. In my opinion, this book has two advantages: one is to run the basic principles of software engineering throughout the book, and the other is simple and easy to understand. For beginners, this book is undoubtedlyVery suitable. Mufasa Title: Data Structures Program Design in C (second edition)Title (Chinese): Data Structure and Progra

strengthen training and education on testing so that everyone can have a correct understanding of testing. Only in this way can we use tools more effectively and efficiently so that testing can truly play its due role. I hope this article will help you in your testing.

principle. Liskov substitution principle (LSP)-Rishi replacement principle Software Engineering guru Robert C. Martin finally simplified the Li's replacement principle into one sentence: "subtypes must be substitutable for their base types ". That is, subclasses must be able to replace them with their base classes. That is, the subclass should be able to replace any location where the base class can appear, and after replacement, the code will work n

getname.Nested Import Nested import: in two cases, one is: this module imports module A (import a), and another Import action is activated if there is an import statement in module, for example, import B, while Module B can import other modules. It is easy to understand such nesting. Note that the local namespace of each module is independent. Therefore, in the preceding example, after the import of module A is complete, this module can only access module, cannot access B and other modules. Alt

history, its power in hand is very limited. The direct propagation of light and reflection and refraction of light are originally the traditional regions of light. However, when the army developed its own theory, it quickly moved to the two battlefields to share the same color with the particles. The theory of volatility is a new theory. The light diffraction experiment of grimadi is the biggest magic weapon for its launch, but it dragged on a heavy burden, that is, the assumption of light and
