This is the 10 point of the dentist. Most people go to the doctor only when they have toothache or uncomfortable teeth. They don’t go to the doctor on time. Some people think that tooth extraction is bad for the brain. Others think it’s partly because of the cost and so on.

IOISo many DP in the early days?
The title requires that one side of the ring be broken. We can break the link into a chain and open a two fold array.
Easy to think of DP, set up\(f_{i,j}\)For interval\([i,j]\)The maximum value is then the interval DP of an enumeration breakpoint.
But there may be negative numbers, which means that there may be two negative numbers in the interval multiply to get the maximum, so let’s say\(g_{i,j}\)For interval\([i,j]\)Minimum value
When transferring, consider all possible situations.

Open config/index.js, set:
autoOpenBrowser: true,（The default is false, changing false to true.
The process of testing the environment is roughly as follows: compose the phar file and modify it to upload any suffix to the server. By controlling the file operation function parameters in index.php, setting the parameters to phar://upload the file name can lead to command execution.
index.phpThe code is as follows
<?php
class foo
{
var $ha = 'echo "ok";';
function __destruct()
{
eval($this->ha);
}
}
$ka = $_GET['file'];
file_exists($ka);
It can be seen that foo is a dangerous class, and when the dangerous object is de serialized, it will cause the command to...
BlueprintFlask framework is one of the way to write multi-module applications, using the flask framework for writing projects, there may be many modules, such as the front and back-end mobile version… If all modules are written in a.Py file, the file will be veryThe bloated, very difficult to maintain, but also not beautiful. So the flask framework introduces the concept of Blueprint (blueprint). A.Py file can be separated into multiple modules.
After the module is separated, the structure is
In this file structure, manage.py is the entry file, the pack...
Preface
Recently I have done several Java Web projects myself, including a company business project and a personal fun project. Write a note summarizing the gains and listing the skills and knowledge needed to do the whole process of doing the project, bringing to you the skills and knowledge that have not really touched the full Java Web.Students of the project have a more complete perspective, providing a so-called “overall situation view”, so that students can learn more targeted. Of course, the example items used here are very elementary and simple, so the gods don’t hav...
It was late at night, and only the lamp in the room was yellowing, and the input cursor in the notebook was blinking.
Work, the project has been completed, but also on the line, this is the second project I was responsible for in the company (product), by their own planning and design of the product, now on the line, although the future operation is also a difficult road, but to go online without a little bit of joy is also false.
In retrospect, there are still a lot of things to think about and improve in the whole process. To sum up, it is just right to sort out the details of knowledge poi...
