Given a tree with n nodes, if you delete a node so that the number of the remaining largest branch nodes is smaller than half of the total number of nodes, the deletion will burst, total number of deleted methods. Solution: Tree DP. the first deep

I. pointer and address description:1. The address operator can only be applied to objects in memory, that is, variables and array elements. It cannot act on expressions, constants, or register-type variables.2. The unary operator * is an indirect

How can I determine whether the CPU of a computer is aligned with the big end or small-character end? First, you must understand what is a big end and a small end. The large-end Mode means that the high bytes of the word data are stored in the low

This program uses C language to read properties files in a format similar to the following. Path =/etc/wgetrclaunch_on_start = true next version goals: (1) Use a pointer to replace two-dimensional data or reduce the capacity of two-dimensional data

Recently, I saw a C language question: Int x, y, I = 3;X = (I ++) + (I ++ );I = 3;Y = (++ I) + (++ I); What are the values of x and y? Answer: It is easy to see the value of x, which is x = 3 + 3 = 6 and I = 5 at the same time. What about y? After

Binary files are relatively small, but not readable. A text file is a readable file. to operate such a file, we need to use the QTextStream class. QTextStream is similar to QDataStream, But it operates plain text files. Some text formats, such as

A friend complained in the comments that the examples in the previous articles were for Windows, and there was no for Linux or for Mac. Let's talk about cross-platform issues today! The so-called cross-platform has two meanings: one is

Now we will provide some cross-platform technologies related to Qt. Using these technologies can make your applications look more in line with the platform's habits. This article is not a complete example, but a lot of small entries. I hope you can

Doxygen is a good tool, but I feel that in mac systems, if the CHM file generated by doxygen is not that appropriate, it should be because CHM itself is a Microsoft product, it is not very common on the Apple system, and file garbled characters

Reducing the MRP data packet size is saving memory space! Since the MRP file is a compressed package of binary compilation, that is to say, the file will be loaded into the memory, occupying only less than KB of memory, so we should try to reduce
