relaxes successfully, it is enqueued. The algorithm ends until the queue is empty.If there is a negative-weight loop, you need to create a count array that returns when the number of points is more than V (the number of vertices).intVis[i]://used to mark whether the point I is in the queue//calculates the shortest short-circuit length of the source point S to each node, where it traverses the adjacent linked list-the chain forward starvoidSPFA (ints)

responsible for defining what commands the recipient needs to execute. The other is the caller (Invoker), which receives the command call and executes the command. But the command pattern also exists insufficient, if the command more time there will be multiple subclasses, resulting in a bloated, can be combined with other patterns of design, such as the combination of responsibility chain mode to achieve the resolution of the command, combined with

AttentionWhen seeking subtrees, the sub-tree DFS sequence is used consecutively, but not in the following way (sub represents the largest DFS order in the subtree of x):void dfs2(int x, int t) { top[x] = t; dfn[x] = ++cnt; subcnt = max(subcnt, cnt); rnk[cnt] = x; sub[x] = cnt; if(!son[x]) return; dfs2(son[x], t); for(int i=last[x]; i; i=e[i].to) { int v = e[i].v; if(v != son[x] v != fa[x]) { dfs2(v, v); } } sub[x] = subcnt;}Because t

. NET responsibility chain model, Singleton mode, template method mode mixPrefaceWow, see the topic is very long, this combination of things, in the end what? This article to ponder together, these two days for the team's software to rush, I am responsible for the piece called: Plug-in Manager. Our team members of the language is quite scattered, I C #, Captain VB.net, there are other members write easy lan

This structure concept, the code in the book almost exclusively pseudo-code, using the abstract data type, this writing can not be run directly on the computer, since the data types are abstract, why not use a template class to implement a linear table.Linear table is one of the most basic data structure, so the application is also extensive, when writing linear table, should try to consider its flexibility, this article uses the doubly linked list s

The cyclic list is another form of chain-type storage structure. Its characteristic is that the pointer field of the last node in the table points to the head node, and the whole chain forms a ring. Circular chain List classification:(1) Single cycle list--in a single linked list, the pointer field null of the terminal node is changed to point to the header node

Chained queue is a kind of storage representation based on single linked listThe head pointer of the queue points to the first node of the single-linked list, and the tail pointer points to the last node in the single-linked list.Exiting an element removes the node from the head pointer, adding the element adds a node at the end of the queueConditions of Use: data element changes relatively large situation. There is no overflow conditionAbstract base class for queues:#ifndef queue#define queue//
