OJ5.2 is very simple, the use of priority_queue to achieve the smallest heap has been OJ ... Every time you encounter a relax problem, simply push it back into a node ...However, the correct implementation should be the following, the key is that the element in the swap heap when using the POS array store changed position after the node number k corresponding to the location in the heap. The following implementation is also very simple, d,v,p are stored in the heap, only POS indicates the locati

At first, it was easy to create an XML document. I just saw that XML is not efficient.In addition, there are different templates, but there is also a small problem, some words such as the time prompt are not sure, and may be minute, day. It is also possible to add s to the plural number.Well, make it an array, but the array has to be made into a variable in the PHP file, and it is difficult to make some extensions (as I know)The final form of a txt text file is also worried about this efficiency

The idea of making XML documents in the first place is easy to do.

reading configuration I think it must be learned, so today we have to learn how to use Python to read the configuration file, Python to read the configuration file here to use the Configparser module, we first look at its basic usage: Common methods: Read (filename): Reading a configuration file Sections (): Getting the section in the configuration file Options (section): Get all option for this section Items (section): Gets all the key value pairs for this section Get (Section,option): G

There is only one root page as the access entry point for the B-tree structure, indicating there must also be indexlevel=1 index pages and indexlevel=0 leaf pages. Because this is a clustered index, the leaf page of indexlevel=0 is a data pa

I guess people who are used to Google search will often change the Chinese and English Google search results. I think this is a waste of time, because I did this before. In Chrome, 1. When the search result page is from google.cn (will at the beginning), you need to change the English search result: copy the keyword, paste the keyword to the address bar, and press enter (Chrome's default address bar is Google search in English) 2. When the search result page is in English, change the Chinese

This example describes the use of HttpWebRequest in C #. Share to everyone for your reference. Specific as follows:The HttpWebRequest class takes advantage of the HTTP protocol and server interaction, usually through get and POST two ways to obtain and submit data. Here are a couple of ways to illustrate the following:GET mode:The GET method completes the data submission by appending parameters to the network address, for example, in address Http://www.jb51.net/?

HttpWebRequest and httpwebrequest The HttpWebRequest class mainly uses HTTP protocol and server interaction, and usually obtains and submits data through GET and POST methods. The following two methods are described as follows: GET Method GET method to complete data submission by attaching parameters in the network address, such as in the address http://www.studyofnet.com /?
