Using namespace STD; This code is written in imitation books. However, compilation and translation fail. There are a lot of compilation errors.

current interval. 　　　　 The code is implemented recursively: voidQueryintk) { if(xTREE[K].R) {ans+=tree[k].sum; return ; } if(TREE[K].F) down (k);//It's good to omit it first. Long LongMid= (TREE[K].L+TREE[K].R) >>1; if(x1); if(y>mid) query (k1|1);} Here's the point: Lazy sign For the interval modification, we waste a lot of time on one of the changes, and modify it is not necessarily to check this point, in order to solve this problem, we

. This is a key point. For simple presentation, it is easier to retrieve data and place it in the shape of a tree. However, it is not easy to add, delete, modify, or delete a tree menu like desktop programming. In fact, I spent a lot of energy here. The first consideration is to implement these functions on your own, but I immediately rejected this stupid idea-now is not an era of "making wheels". I must learn to stand on the shoulders of giants. Therefore, we decided to select a mature JS tree

Simple parameter configuration for flexible functions 1 DtreeDtree is a JS open-source tree component, use is particularly simple, you can open new links according to the tag, custom display icons and so on. The advantage is that the function is simple and practical, but does not support checkbox, does not support dynamic increment, delete node, move node. Of course, if you can use other things like jquery can be added dynamically, but this adds more code. References:A official website

Use hibernate to implement unlimited CLASSIFICATION OF TREE STRUCTURES In the system, infinite tree structure classification is often used, such as Organization Management and Product/Region Classification. Generally, the following two methods are used:One is similar to Struts-menu (http://struts-menu.sourceforge.net) XML file management method, configuration is more convenient, but it is difficult to integrate with other applications in the system;The second is to use databas

js| algorithm It's a bit of a hassle to implement a tree structure on a Web page.In the recent development of an MIS system, our project team has used a lot of tree structure: for example, the choice of personnel, the choice of units to wait.The database used by this MIS system is Oracle 9i. Oracle 9i SQL supports iterative queries. Our tree is written by the Ox, butAlso refer to the network of more famous XTree (can be downloaded here: http://webfx.

to see and is a compiler bug. Fix to xstring The string in P. J. STL adopts the copy on write and reference counting technologies. For the following code:String S1 = "ABC"; // Statement 1 String S2 = S1; // Statement 2 S2 = "123"; // Statement 3 When Statement 2 is executed, there will be no two "ABC" copies. Instead, S2 shares the memory with S1. When Statement 3 is executed, the S2 value is rewritten, and memory is allocated separately. The method to implement this is to reference the count.
