问题 Can you return addWord part which will add word the list alphabetically?i tried but it didn't work.I'm very new at C programming.Actually,i'm working on it since one week but i can not the problem. typedef struct NODE { char *str; int count; struct NODE *pNext; } NODE; void addWord(char *word) { NODE *pCounter = NULL; NODE *pLast = NULL; if(pStart == NULL) // pstart is globally defined pStart=NULL; { pStart = createWordCounter(word); return; } /* If the word is in the list, increment its

问题 Sup guys so I'm going over a few of my methods in my Linked List class and I'm getting a logical error when removing a node from a linked list. I was working on my removeFirst() method when I then encountered a error in my removeLast() method as well. The problem is that both remove the last item in the list. not sure why but here is my code. Remove First Node public T removeFirst() throws EmptyCollectionException { // Checking to see if the List is empty or not if ( isEmpty() ) throw new

问题 I'm trying to display the titles of all descendants of a jsTree parent in a separate div (.childNodes) when an item is selected in the tree. My issue is that the descendants are seemingly being lazy loaded, and are only rendered in the DOM when a node is expanded, not when it is selected. Is there a way to disable this to render all nodes before the parent is expanded? This is how I'm creating the tree: container.jstree({ 'core': { 'data': { 'url': nodesContent, } }}); And this is how I'm

问题 I keep getting a crash that says: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'CCSprite: Batched sprites should use the same texture as the batchnode' I am not quite sure what this means. I googled the crash but got no results. Also this only happens when I go back to my first scene after coming back from the second scene in my game. I double checked my code and I make sure all the images in my sprite sheets are added as children to the batch node

问题 I have a program that contains a TreeView. All of my nodes except for the root and two nodes under the root are loaded from a database. When the user adds data to the database it must be automatically added to the TreeView. I can successfully do this by clearing all the nodes, add the default nodes and add all the data including the new one to my TreeView, but all nodes of the new TreeView are collapsed. Our client wants to retain all expanded nodes but still add the new data he just added.

问题 I have an XML file where the nodes that I need the data from are all named the same. I understand how to access the first (or second record) so the following query only gives me the second author (the <a1> tag). How do I get all the authors as a single column ? DECLARE @MyXML XML SET @MyXML = '<refworks> <reference> <rt>Journal Article</rt> <sr>Print(0)</sr> <id>869</id> <a1>Aabye,Martine G.</a1> <a1>Hermansen,Thomas Stig</a1> <a1>Ruhwald,Morten</a1> <a1>PrayGod,George</a1> <a1>Faurholt

问题 I've been able to create a proof that shows the maximum total nodes in a tree is equal to n = 2^(h+1) - 1 and logically I know that the height of a binary tree is log n (can draw it out to see) but I'm having trouble constructing a formal proof to show that a tree with n leaves has "at least" log n. Every proof I've come across or been able to put together always deals with perfect binary trees, but I need something for any situation. Any tips to lead me in the right direction? 回答1: Lemma :

问题 I'm trying to only show the node text on mouseover. When I mouseover the node, I have the opacity for the svg circle changing, but only the text for the first node showing up. I've figured out that this is because of how I'm using the select element, but I can't figure out how to pull the correct text for the node that I'm hovering on. Here's what I currently have. node.append("svg:circle") .attr("r", function(d) { return radius_scale(parseInt(d.size)); }) .attr("fill", function(d) { return d

问题 I was wondering what exactly a node is in JavaScript? As in the functions: element.nodeType row.parentNode.removeChild(row); 回答1: A "node", in this context, is simply an HTML element. The "DOM" is a tree structure that represents the HTML of the website, and every HTML element is a "node". See Document Object Model (DOM). More specifically, "Node" is an interface that is implemented by multiple other objects, including "document" and "element". All objects implementing the "Node" interface
