value type and calling convention unchanged), the replacement DLL file will not have any impact on the EXE file, thus greatly improving the maintainability and extensibility;(3) programs written in different programming languages can call the same DLL function just according to the function calling convention;(4) Suitable for large-scale software development, make the development process independent, the coupling degree is small, facilitates the development and the test between different develo

as much secondary space as the sequence to be sorted. Using it to merge two ordered sequences will have unparalleled advantages. Its time complexity is O (nlog2n) in both the best and worst-case scenarios. Not sensitive to the order of the data. If data node data is large, it will not be suitable. But you can change the index operation, the effect will be very good.Heap ordering: Because it is based on the direct selection of the order of the use of

Advantages and disadvantages of ASP. NET WebForm and MVC, asp. netwebformmvc Posted on my personal website, please clickRead! Differences between aspnet mvc and WebForm MVC vertically splits the code in the development process from the server to the browser, and the coupling between layers is very low, because it is encapsulated along the underlying development context, therefore, developers can understand

linked list is better than an array:1. Insert and DELETE operations. Assuming that an element is inserted in the middle of the array, the memory address of all the elements behind the element will be moved backwards. The same is the case with the deletion. Only when the last element of the data is inserted and deleted. It's quicker than that. The list simply needs to change the node information within the node that is necessary to change it. There is no need to change the memory address of the
