The stm32-M3 has a system time base timer, which is a 24-bit descending counter. After the system time base timer is set and enabled, the counter is reduced by one every time the system goes through a clock cycle. When the counter is reduced to 0,

This question seems to be easy to build. In fact, the maximum flow with bare minimum cost will inevitably Time Out, And the zkw billing flow will also time out. Therefore, you must understand the meaning of the question. The question must be better

Give you a tree and mark it as 1 ~ N, each edge has a certain edge weight, so there is a maximum distance from each vertex num [I];First obtain the num [] array, and then there are 500 more queries. For each query, enter an integer m, evaluate the

Question 4 Question: enter an integer and a binary tree.Access from the root node of the tree to all the nodes that the leaf node passes through to form a path.Print all paths equal to the input integer.For example, enter the integer 22 and the

There are many articles about traits, but I feel that most of the articles are obscure, and the application description of a less complex C ++ template is too complicated. I can't help but want to share my understanding with you. Maybe I have

Function templates are widely used in actual programs because of their own characteristics: After defining a function body, you can call them multiple times for instantiation.Example:[Cpp]# Include Using namespace std;Template // function template

Given an order for n kinds of products, each product has an initial price pri, the initial quantity numi, and then the m combination, these combinations will get a cheap price. Finally, I asked how to make the total price the least. Solution: I

I. ExamplesA two-dimensional array can be replaced by a pointer pointing to an array, while a pointer array can be replaced by a pointer pointing to a pointer.[Html] view plaincopy# Include Using namespace std; Void main (){Char * a [] = {"Hello",

The optimal matching of a bipartite graph. Find the minimum billing flow. The minimum cost for matching all vertices is required. simply apply the KM algorithm .. The following is the 1853 AC code:[Cpp]# Include # Include Using namespace std;Const

Different colors overlap to produce different colors: RG, RB, BG, RGB, calculate the area of each color.Rectangular area and enhanced scanning line. The line segment tree records the length of 7 colors respectively, and then records the number of

Some time ago, I need to figure out IROM. It is mainly because Nandflash needs to be replaced, while the IROM provided by alicloud only supports 2 GB and does not support 4 GB. So you need to give it to yourself. IROM is an nb0 binary file. It is

First, declare that this is an excerpt. In order to obtain the page views, the original address is the original address. 1. When declaring a character array, the number in [] should be the number of characters in the array, including '/0'For example,

Ideas: Ask for the maximum volume of the potion that can be detoxified as long as the concentration of the potion is lower than the given value. I think this is a greedy question. Because the volume is the same, the concentration is sorted from

I found that the first time I read a book, I cannot clearly understand the nature of the problem. We still need to go back and summarize it. Therefore, I decided to write a summary for each part of the book in the future, on the one hand, you can

[Cpp]/**1. Use the stack to implement the number conversion, requiring Programming to Implement the following functions:A. compile the SqStack file. h. Define the stack template SqStack, as well as the inbound, outbound, and read stack top elements

After more than a year of plug-in Development, I am familiar with the working mechanism of plug-ins. During the development of plug-ins, I used np_entry.cpp, npn_gate.cpp, npp_gate.cpp, and pluginbase In the sdk. h these files greatly improve the

Today, I am bored occasionally. When I see something called the "China Surplus Theorem", I think it is fun to write a summary of the question first. Suppose that a number (1) is divided by 3 and 2, (2) divide by 5 and 4, (3) divide by 7 and 6, and

For example, if 6 is divided into the following 11 types, p (6) = 116; 5 + 1; 4 + 2, 4 + 1 + 1; 3 + 3, 3 + 2 + 1, 3 + 1 + 1 + 1; 2 + 2 + 2, 2 + 2 + 1 + 1, 2 + 1 + 1 + 1 + 1; 1 + 1 + 1 + 1 + 1 + 1; in all the partitions of positive integer n, the
