nodes

问题 I've been using iGraph to determine staff community structures within the 2002 Enron corpus. I've extracted a subset of only 50 employees, and am plotting this subset using various community detection algorithms. The problem is that when I use the plot function, numerous nodes will overlap across different communities (communities being defined by colour of node, and colour bubbles). Example: I want to keep the colour bubbles, however dont want any to overlap. I've tried all the different

问题 Im just trying to write a simple function to addd a friend to a UserAccount list. All the information is provided through the parameter. If the user is already in the list I do not need add him again but display records saying he is already in list. I wrote this piece of code. not sure if this is correct, any suggestion to improve the code? Does this work? int add_friend(UserAccount* user, char Circle, UserAccount* friend) { struct UserAccountNode *p; p = (struct UserAccountNode *) malloc

问题 I have a practice question that I'm stumped on - to get the number of leaf nodes in a binary tree without using recursion. I've had a bit of a look around for ideas, I've seen some such as passing the nodes to a stack, but I don't see how to do it when there's multiple branches. Can anyone provide a pointer? 回答1: NumberOfLeafNodes(root); int NumberOfLeafNodes(NODE *p) { NODE *nodestack[50]; int top=-1; int count=0; if(p==NULL) return 0; nodestack[++top]=p; while(top!=-1) { p=nodestack[top--];

问题 I need to get the size of a tree using: size(Tree,Size) What I have so far is wrong, please advise! size(empty, Size). size(tree(L, _, R), Size) :- size(L, Left_Size), size(R, Right_Size), Size is Left_Size + Right_Size + 1. Output should produce: ?- size(node(1,2),X). X = 2. ?- size(node(1,[2,3,4]),X). X = 2. ?- size(node(node(a,b),[2,3,4]),X). X = 3. 回答1: Prolog is a declarative language, you must state correctly your patterns: size(node(L,R), Size) :- ... % why you add 1 to left+right

问题 My minimal reproducible example: #include <stdio.h> #include <stdlib.h> typedef struct NodeStruct Node; //struct for each office item struct NodeStruct { int id; struct NodeStruct *next; struct NodeStruct *prev; //Create doubly linked list node }; /** Structure for the whole list, including head and tail pointers. */ typedef struct { /** Pointer to the first node on the list (or NULL ). */ Node *head; Node *last; } List; List *list; List *makeList(); static void *addRecord(List *list, int

问题 just like the title I need help in a php script gets "name" node value , if it equals specified given value ; changes "rate" node value has its same "person" parent node. the xml file 'rate.xml' like the following <?xml version="1.0"?> <user> <person> <name>jessy</name> <rate>2</rate> </person> <person> <name>mice</name> <rate>5</rate> </person> </user> the script will be similar to this <?php $name = $_POST['name']; $like = $_POST['like']; $doc = new DOMDocument(); libxml_use_internal_errors

问题 I just started a project for my Java2 class and I've come to a complete stop. I just can't get my head around this method. Especially when the assignment does NOT let us use any other DATA STRUCTURE or shuffle methods from java at all. So I have a Deck.class in which I've already created a linked list containing 52 nodes that hold 52 cards. public class Deck { private Node theDeck; private int numCards; public Deck () { while(numCards < 52) { theDeck = new Node (new Card(numCards), theDeck);

问题 So I ran into a problem with lag on a platformer game I'm building. So I'm researching how to improve performance. I'm trying to do batch drawing, so that there is less draw calls. I'm having issues though. So with a brand new project: I have 4 hero sprites, all images are stored in a .atlas folder. so there is a 1/2/3x image for each sprite in the atlas folder. I drag and drop that into the xcassets folder. Then I go to my sks file create 4 sprites and change the texture accordingly. By

问题 Is it possible to get a p-value for nodes in a categorical tree analysis with R? I am using rpart and can't locate a p-value for each node. Maybe this is only possible with a regression and not categories. structure(list(subj = c(702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L, 702L), visit = c(4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L), run = structure

问题 I'm working on a website that uses hierarchical data. After struggling to do it with MySQL databases (really complicated...), I decided to dive into XML because it sounds like XML works perfectly for my needs. Now I'm experimenting with an XML File and SimpleXML. But first of all, here is what my XML File looks like: <?xml version="1.0" encoding="ISO-8859-1" ?> <content> <parent> <child id="1"> <title>child 1</title> <child id="1"> <title>child 1.1</title> <child id="1"> <title>child 1.1.1<
