Enter the scores (Chinese and mathematics) of a group of students and classify the students. The grading method is to define the scores of one subject and one subject is higher than or equal to B, in this case, the level of A should be better than that of B. Each time, the level of A should be removed as the level, and the level of A should be downgraded, and so on. Enter the student I
I did not know how to write it after reading what little_w wrote. After reading the question, I found that I understood it wrong. There is a neighboring in it, this means that when you specify a task, you specify a continuous segment in the original sequence.
Then there is how to implement DP. A new DP model DP [I] [J] indicates whether the previous I Robot has shared the feasibility of J tasks and can act 1, 0. so for a current DP [I] [J], you can set the current value to exist as long as a val
ID with the "-" number:
$query = new Wp_query (' cat=-12,-34,-56 ');
Multi-category Query
To get an article with multiple classifications at once, the following code gets an article that must have a category with IDs 2 and 6 at the same time:
$query = new Wp_query (Array (' category__and ' = = = Array (2, 6)));
Get Articles with multiple classifications, without their subcategories, and the following code gets an article with an ID of 2 or a category with ID 6:

This article provides a detailed analysis of the code for loop deletion of infinitely classified subnodes in PHP. For more information, see
The code is as follows:
Private function _ deleteSubNode ($ ids ){
$ SubNodes = array ();$ Mod = D ('node ');Foreach (explode (',', $ ids) as $ k ){$ Res = $ this-> _ getSubNode ($ k, $ subNodes [$ k], $ mod); // Obtain the subnodeIf (! Empty ($ res [0]) {Foreach ($ res as $ k => $ nid ){$ Mod-> where ('I

I will answer more questions about readers this month. I will discuss issues such as Windows Communication Foundation WEB services running under a common user account and the use of classified technology and dual key control to protect credit card data.
Q: When I run a simple windows®communication Foundation service as a non-administrator, why can't I start?
A: The first thing I want to say is, it's nice to hear you test your code under a normal use

For the classified information Web site, there is already a very good program UI interface results, but for a new site, copy the mature structure of the site is not necessarily a good thing, because your site content and users are uncertain, so for the initial classification of information sites, the more simple the interface to do less likely to effect better.
A few days ago a friend did a similar net like the classification of information sites, thi

For a long time, we all think that a trojan is an executable file ending with an exe, as long as it does not run a file suffixed with an exe. However, if Trojans are easily identified, they cannot be called Trojans. In fact, many Trojans are not suffixed with exe. For example, the famous backdoor Trojan tool bits is a dll backdoor. The whole backdoor program has
All along, we think Trojan is the end of EXE executable file, as long as not run exe as a suffix of the file can be. But if the Trojan is so easy to distinguish, it can not be called a Trojan. In fact, there are many Trojans are not the suffix of EXE, such as the famous backdoor Trojan tool bits, is a DLL back door, the entire backdoor program has only one DLL file, but can achieve very scary effect. So how
This article will introduce a very short code, but also a very covert backdoor Trojan, so that everyone in the detection program can avoid being hung Trojan. The contents of the file are as follows: Many comments are inserted into the code, and the server's detection procedure is difficult to detect if it is not rigorous. After the comment is removed, the code is as follows: The actual code that was actually executed was: the back door was used to exe
