I will put some main knowledge points that need to be used next to the introduction of the algorithm, and I introduce an algorithm by solving a problem rather than directly; First: find the most value in an array Challenge arena method: const int inf=10e9; int main(){ int n; scanf("%d",&n); int min=inf,max=-inf;//Set the ma ...

1. Get key code There is little difference between mouse and keyboard in code implementation, so we can imitate the other as long as we complete one of them. Because after pressing a key before, nothing else can be done. Modify init inthandler21 function in C #define PORT_KEYDAT 0x0060 / / the device number is specified by IBM. For detail ...

To realize the three chess game In the initial work, an identifier is defined by #define to represent a constant (the horizontal and vertical coordinates of the chessboard) (because there are many coordinates that need to be used in the writing of the code. When reading the code, the reader may be tired of understanding what the current value ...

Operation of Linux kernel queue This system imitates the queue implementation in Linux. It is a two-way linked list. Personally, I think the implementation of two-way linked list in Linux is simply wonderful. 1, Implementation of conventional linked list When learning the data structure course, they all learned the data structure of two- ...
