Original address: 77431043First, explainIn the graph G, if there is at least one mutually accessible path between the two vertices, the two vertices are strongly connected (strongly connected). If there is strong connectivity to every two vertices of the graph G, the G is a strongly connected graph. The strongly connected

Timestamp Dfs_clock: It's plain to note that the order in which each node is accessed is recorded. Suppose we use the pre to save, then if Pre[u] > Pre[v], then we can know the first to access the V, after access to U.Now given an edge, (U, v), and the ancestor of U is FA, if there is pre[v] 1 to find the connected component:A mutually accessible node is called a connected component;#include 2 cutting top a

Compared to the algorithm used to calculate the nodes for an undirected graph, the algorithm only has one more stack to store all the edges without any nodes. When the nodes are shut down, all the edges are popped up for storage.

Detailed explanations and differences between Left-connected and right-connected MYSQL and internal-connected mysql
Difference between left and right connections and internal connections of MYSQLHere, we will go through an example to explain these concepts clearly.

Type 1 is based on ISO 14443 A and are currently available exclusively from Innovision Technology (topaz™). It has a 96-byte memory capacity, which makes it a very cost-efficient tag for a wide range of NFC applicationsType 2
ancestor's two leaf nodes, so that the two nodes can contract all the points on the path of the ancestor, because the formation of a ring must be dual-connected. Then we can find two leaf nodes with the farthest recent common ancestor. This one is exactly the same as (leaf + 1)/two times, and all the points are reduced together.
3. Find the nearest common ancestor (LCA)

The model is very simple, the road under construction we can think that side was deleted. Then a graph G is able to delete any edge, still connec
HTML tag semantics, the relevant content online there are many. You can go to study and see if the label you are using has the meaning that it really wants to express, do you use the right label? Today's introduction is the use of B-tags, or strong tags , translated from http://www.think-ink.net/html/bold.htm.
There is a difference between using what's referred to as logical tags and tags that primarily affect visual layout.

At first, I believe that every one will feel a bit puzzled, mainly because the word "weight", of course, if only to understand and use the two terms, you do not have to care about this irrelevant word.Well, it's time to talk. The so-called double connectivity and strong connectivity, the biggest difference, but also the most essential difference is that the former applies to undirected graphs, while the latter applies to the undirected graph. The concept of the two is the same, that is, a point,
