The DFS (depth-first-search) Depth-first search algorithm is a very common kind of algorithm in graph traversal algorithms. Share to everyone for your reference. The specific method is as follows:
#include
To write Dfs in a different way. The specific code is as follows:
#include
The iterative traversal algorithm for DFS is as follows:
text filestructured(structured) as follows:
1.
The first line contains a
positive
integer (integer) which shows the number of mazes to be painted.
2.
The rest of the file contains the mazes.
the lines of the Input file can be of different length. The text which represents a maze Isterminated (termination) by a separation line full Of Underscores (bottom line) (' _ '). There is at the most of lines and a
Breadth-first traversal is a traversal strategy for connected graphs. The basic ideas are as follows:
1, starting from a vertex V0 in the graph, and accessing this vertex;
2, from V0, access to the V0 of the w1,w2,...,wk of the neighboring points; then, from the W1,w2,..., Wk to access their inaccessible neighboring points;
3. Repeat step 2 until all the vertices
call. Each call was represented by and names, separated by a single space. Names is first Names only (unique within a data set), is case sensitive, and consist of the only alphabetic characters; No name is longer than letters.For example, if Ben called Dolly, it would is represented in the data file asBen DollyInput is terminated by the values of zero (0) for N and M.OutputFor each of the input set, print a header line with the data set number, followed by a line for each calling circle in that
Depth-first traversal in the adjacency table of graphs: a hash table is needed to assist.
The specific implementation code is as follows:

Well, the deep and wide search graph traversal is the course on the data structure that day. Then, in the evening, we asked for various online learning methods for the key of the data center, then the next night I changed the library for one night with the printed program, and then I went back to the dormitory to adjust the program. ...... Amount ...... In this case, I also called the teacher and said that

parameters: the first is the index of the member or array of the object, and the second is the corresponding variable or content. If you need to exit each loop so that the callback function returns false, the other return values are ignored.
Parameters
Objectobject
An object or array that needs to be repeated.
Callback (optional) Function
The callback function that each member/element executes.

Graph Visualization Library in JavaScriptI ' ve just put together what's be looking for:http://www.graphdracula.netIt ' s JavaScript with directed graph layouting, SVG and can even drag the nodes around. Still needs some tweaking, but is totally usable. You create nodes and edges easily with JavaScript code like this:v
This article mainly introduces how to write a hotspot graph in javascript. A hotspot graph is displayed in the form of a vertex. By supplementing the surrounding color, the gradient will be adjusted accordingly, if you are interested in hotspot maps, refer to gis. If you use js to write hotspot maps, how can you do this without using the background, as is easier
