coding point of view is as follows: TCP communication requires server-side listening Listen, receiving client connection request accept, waiting for client connect to establish a connection before sending and receiving packets (recv/send). However, the concept of UDP server and client is not obvious, the server side is the receiving end need to bind the port, waiting for the arrival of the client's data. Subsequent data can be sent and received (RECVFROM/SENDTO) work. Reference: http://blog.

When encountering this problem, it is not easy to think quickly, it may be easier to think of the idea of recursion;But how exactly do you write it?In fact, this problem is equivalent to the graph theory in the connection graph, it is easy to think of is depth-first search or breadth-first search;We use the depth-first algorithm to find the problem;Directly ask for a few areas are not good, then we change a way to beg, this problem is so, direct beg, but when we switch ideas after the enlightene

In addition to the simplest drawing curve function I used above, it has other very powerful features, as shown in: It contains many examples of many kinds of chart drawing, which can be used by the program apes to achieve a variety of data visualization operations. But I do not know why, Lightningchart this powerful. NET component in the network introduction is very few, to me

Algorithms for basic graphsG= (V,e)notation, adjacency Matrix, adjacency list (sloppy view)The adjacency list represents a containing | An array of v| linked lists Adj, each node has a linked list. For each node u belongs to V, the adjacency list Adj[u] contains all theJunction U has a node v connected to the node.Weight graph, with a related weight for each edge in the graph.The weight function w:e->r.The adjacency list flaw is the inability to quickly determine whether an edge (u,v) is an edge

The main topic: to find the minimum point of two-dimensional coverage and maximum independent set.Title Analysis: If a point is selected, then all edges connected to this point are overwritten, so that the minimum point set that all edges are overwritten is called the minimum point overlay, which equals the maximum match, and the largest point set with no edges connected between any two points is called the maximum independent set, which equals the total number of nodes minus the maximum number

relationship and extend the relationship are the same arrows, which can be distinguished only by writing a text above, and translated into other languages, almost without knowing what it means. The arrow facing the extended relationship is also difficult to understand, why point to the base use case, not to the extension caseVS2010 adds a "project" element that is a good innovation to associate word,excel these documents in a use case diagram. But why not integrate these functions directly into
