Reverse doubly-link list in C++

由 南楼画角 提交于 2019-12-07 13:27:29
问题 I've been trying to figure out how to reverse the order of a doubly-linked list, but for some reason, in my function void reverse() runs while loop once and then crashes for some reason. To answer some questions ahead, I'm self-teaching myself with my brothers help. This isn't all of the code, but I have a display() function which prints all nodes chronologically from start_ptr and a switch which activates certain functions like case 1 : add_end(); break; case 2 : add_begin(); break; case 3 :

Reversing order of items in DOMNodeList

由 点点圈 提交于 2019-12-07 07:39:28
Hello I'm making RSS reader and I'm using DOM. Now I stuck, trying to reverse the order of the items in the DOMNodeList. I can make it with 2 cycles - one to make it as array and one for rsort() . Is there any way to reverse the order in the DOMNodeList or must be done with "the array way"? There is no method for reversing a DOMNodeList. But you can keep it as it is, and if you need it, walk through it from the end to the start. Example: <?php $doc=new DOMDocument; $doc->loadXML(' <div> <span>1 <span>2 <span>3 </span> </span> </span> </div>'); $nodeList=$doc->getElementsByTagName('span'); for(

Is there an inverse function to jQuery serialize?

由 こ雲淡風輕ζ 提交于 2019-12-07 06:15:36
问题 I can write something, I'm asking if something is already built into jQuery. 回答1: No there is not. How would you know which DOM element to change? There could be the same elements with the same name in different forms etc'. Maybe parseJSON will help you: jQuery.parseJSON(json) Returns: Object Description: Takes a well-formed JSON string and returns the resulting JavaScript object. 回答2: Short Answer: No , there isn't something built into jQuery to do this. Not sure why not... But here is a

Reverse order of words in string

由 核能气质少年 提交于 2019-12-07 03:53:34
问题 I am preparing for an entry-level job interview. I am trying to reverse the order of words in a string, but my output is a bunch of junk that makes no sense. I think the problem may be because I'm using "char*" for my functions? Anyways, heres my code #include <iostream> #include <string> using namespace std; char* reverse(char* str, int a, int b); char* reversewords(char* str); int main() { char str[] = "The interview is"; cout<<"Reverse is: "<<reversewords(str); cin.ignore(); return 0; }

list.reverse() is not working [duplicate]

由 怎甘沉沦 提交于 2019-12-06 22:30:03
问题 This question already has answers here : Unable to reverse lists in Python, getting “Nonetype” as list (3 answers) Closed 2 years ago . I honestly just don't understand why this is returning None rather than a reversed list: >>> l = range(10) >>> print l [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> print l.reverse() None Why is this happening? According to the docs, I am doing nothing wrong. 回答1: reverse modifies the list in place and returns None . If you do l.reverse() print l you will see your list

Django reverse lookup chaining queryset

由 梦想与她 提交于 2019-12-06 21:30:29
I have several models that I need to do reverse lookups in, then somehow chain the querysets together. I got 3 models, (1) designers create (2) projects, and projects contain (3) uploaded images. Models class Designer(models.Model): ... class Project(models.Model): designer = models.ForeignKey('Designer') class UploadedImage(models.Model): project = models.ForeignKey('Project') So a designer opens up his page and wants to see all his projects and some images associated with his projects, I could do something like, d = Designer.objects.get(id=2) projects = d.project_set.all() But then with

Reverse print an array in assembly programming

I need to reverse print a string array in assembly language. Following is my code. proc reverseAr mov cl,count mov si,offset Ar mov si,3 write2: mov dl,Ar[si] mov ah,02h int 21h dec si loop write2 ret endp But this doesnot give the answer. Can anybody tell me what is the exact meaning of si? Is it not the index of the array position? proc reverseArray mov cl,count dec cl dec si printRevArr: mov dl,arr[si] add dl,48 mov ah,02h int 21h dec si loop printRevArr ret endp Do not use mov si,offset Ar .It will reset the array indexes. si means source index register. It can be used as pointer. it is
