nodes

I'm trying to create a simple singly linked list. Previously, I successfully did this with no errors, however now I encounter an error. I suspect that there is some kind of problem with memory allocation because of the if statement in line 23. What I've tried: I used typecasting in all of my declarations even though it is not necessary in C. I removed the if statement and I still encountered the errors. Here's my code: #include <stdio.h> #include <stdlib.h> typedef struct { int value; struct Product *next; } Product; int main() { int user_choice; Product *head; head = malloc(sizeof(Product));

is anyone familiar with networkx? I try to get a hypergraph, where i want to set the Hyperedges as other colored nodes (size dependent on their value) out of an list. And i want to set the Nodes out of an other list. The documentation and examples on the networkx website are really spare, but i am sure it is possible. I started with this example , but this is only an example for different edges. Can someone tell me how i can put up two different set of nodes with different color/size in networkx? Did you want something like this use nx.draw_networkx_nodes using nodelist parameter: # Author:

Is there a way to detect DOM change events? whether it be text replacement, moving a node, removing or adding a new node, etc. Ansel Santosa I think what you're looking for is DOMSubtreeModified Edit: upon further inspection this and other MutationEvents have been deprecated by the W3C but there doesn't appear to be a replacement until DOM Level 4 See: "Why is the DOMSubtreeModified event deprecated in DOM level 3?" Long story short, DOMSubtreeModified will still work and there is no reasonable alternative implemented across stable browsers. 来源： https://stackoverflow.com/questions/8733306

i have an nested tuple like this: mostfrequent = (('16.37.97.17', '178.237.19.228', '55177', '443', '6', '1', '46'), ('16.37.97.17', '178.237.17.97', '44492', '443', '6', '1', '46'), ('16.37.97.29', '178.237.17.61', '56326', '443', '6', '1', '46'), ('16.37.97.222', '104.131.44.62', '60179', '80', '6', '2', '620'), ('16.37.93.196', '16.37.157.74', '2049', '691', '6', '1', '100')) I want to draw every element of every subtuple with networkx declared via nodelist: nx.draw_networkx_nodes(G, pos, nodelist=flattened_list_nodes, node_size=1600, node_color='blue', alpha=0.6) For that i flattened the

I have created a linked list struct in c struct node{ int value; struct node* next; }; a method to add a node at the start of the list : void addFirst(struct node *list, int value){ struct node *new_node = (struct node*) malloc (sizeof (struct node)); new_node->value = value; new_node->next = list; list = new_node; } I create a list (malloc and everything), then call this method, it adds the new node inside the method but when i get back to my main my old list remains unchanged. Using DDD debugger to check everything. How is this possible? I am not able to change the method signature so it has

I am new to using XSLT. I want to display all of the information in an xml tag in my xsl formatted page. I have tried using local-name, name, etc and none give me the result I want. Example: <step bar="a" bee="localhost" Id="1" Rt="00:00:03" Name="hello">Pass</step> I would like to be able to print out all of the information ( bar="a" , bee="localhost" ) etc as well as the value of <step> Pass. How can I do this with xsl? Thank you! If you want to return just the values, you could use the XPath //text()|@* . If you want the attribute/element names along with the values, you could use this

I am trying to select the inner text of a td with an id attribute with the HTMLAgilityPack. Html Code: <td id="header1"> 5 </td> <td id="header2"> 8:39pm </td> <td id="header3"> 8:58pm </td> ... Code: HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument(); doc.LoadHtml(data); var nodes = doc.DocumentNode.SelectNodes("//td[@id='header1']"); if (nodes != null) { foreach (HtmlAgilityPack.HtmlNode node in nodes) { MessageBox.Show(node.InnerText); } } I keep getting null nodes because I am not selecting the td tag correctly but cannot figure out what I have done wrong... Edit: I made

I have dataset which has more than 50k nodes and I am trying to extract possible edges and communities from them. I did try using some graph tools like gephi, cytoscape, socnet, nodexl and so on to visualize and identify the edges and communities but the node list too large for those tools. Hence I am trying to write script to exact the edge and communities. The other columns are connection start datetime and end datetime with GPS locations. Input: Id,starttime,endtime,gps1,gps2 0022d9064bc,1073260801,1073260803,819251,440006 00022d9064bc,1073260803,1073260810,819213,439954 00904b4557d3
