The linked list node is defined as follows: struct listnode {int m_nkey; listnode * m_pnext;}; analysis: This is a very interesting interview question. This question and its variants often appear in interviews and pen questions of major companies. After seeing this question, the first response is that t

procedure and a trigger Triggers are very similar to stored procedures, and triggers are also sets of SQL statements, the only difference being that triggers cannot be invoked with an EXECUTE statement, but are automatically triggered (activated) when a user executes a Transact-SQL statement. A trigger is a stored procedure that executes when a data in a specified table is modified. Pass- through creates triggers to enforce referential integrity and

Sword refers to Java Implementation of offer programming questions -- interview question 13 deletes linked list nodes in O (1) time, and sword refers to offer Question: given a one-way linked list head pointer and a node pointer, define a function to delete the node at O (1) time. Given a one-way linked list, the time complexity of normal Chain List deletion is the time complexity of searching the linked li

nonatomic and atomic: your understanding of them.29. Communication Methods between two objects30. How to store OS data? Does the SQLite database support writing data from multiple threads? If not, how can this problem be solved?31. If a function is executed for 10 times and the secondary result is incorrect for eight times, how should you check the bug.32, 1-1000 digits, the order is disordered, and three

ASP, PHP, and JSP pages require additional language engines to analyze and execute program code. The execution result of the program code is re-embedded into the HTML code and sent to the browser together. ASP, PHP, and JSP are all Web server-oriented technologies. client browsers do not require any additional software support.3. What about mvc? A: An application completed by a Model, View, and Controller sends the functions to be implemented by the Model to the Controller, and the Controller r

, the connection file is unavailable. 11. What commands are available to view the file content? What are their respective features? More: You can only view the last part of the file. It is inconvenient to flip the page. Less: it is easy to flip pages and frequently used to view large file content. Cat: The content is relatively small. Cat-n lists the row numbers by the way. 12. What are the common formats of compressed packages in Linux? What are their respective features? How to compress dire

Interview Questions: ASP. NET 1. Describe the role of inetinfo.exe, aspnet_isapi.dll and aspnet_wp.exe in the page loading process. Inetinfo.exe is the Microsoft IIS server running, handling ASP. net requests among other things. when an ASP. NET Request is already ed (usually a file. aspx extension), the ISAPI filter aspnet_isapi.dll takes care of it by passing the request tothe actual worker process as

1. In the sorting array, find the number of occurrences of a given number. For example, in [1, 2, 2, 2, 3], 2 appears three times. The binary search method is used to locate the start and end positions of a given number. In the worst case, the time complexity is O (logn ).The method is straightforward, but it is still difficult to write the code. If you are interested in xdjm, you can practice it. 2. Reverse Order of a one-way linked list# Include Typedef struct snode {Char

constructor cannot be a virtual function. To construct an object, you must know exactly what to construct. Otherwise, you cannot construct an object.The Destructor can be pure virtual functions.10. Problems Related to the copy constructor, such as deep copy, shortest copy, and temporary objects.Deep copy means that the resources and pointers are copied, while the light copy only copies the pointers and does not copy the resources.In this way, the two pointers direct to the same resource, causin

the reuse of the cell without confusion. After the data is configured, by updating the constraint, the frame of the last control can be determined only by determining the height that the cell actually needs, and caching it, the next time it is acquired, the judgment exists, and if it exists, it returns directly. Therefore, it is calculated only once.20. How does the UITableView calculate the content height? Why does the proxy method that gets the row
