问题 Delete nodes which have a greater value on right side Given a singly linked list, remove all the nodes which have a greater value on right side. Examples: a) The list 12->15->10->11->5->6->2->3->NULL should be changed to 15->11->6->3->NULL. Note that 12, 10, 5 and 2 have been deleted because there is a greater value on the right side. When we examine 12, we see that after 12 there is one node with value greater than 12 (i.e. 15), so we delete 12. When we examine 15, we find no node after 15

问题 digraph foo { a [label="<first> A | <rest> rest", shape=record]; b [label="<first> B | <rest> rest", shape=record]; a:rest -> b [label="foo", arrowtail=dot, dir=both]; } I would like to start the tail of the edge (a to b) from within a:rest (ideally in the center), is this possible? I am trying to draw linked lists using box and pointer like notation. 回答1: Yes, this is possible. The attribute to use is called tailclip: If true, the tail of an edge is clipped to the boundary of the tail node;

问题 I know bubble sort is probably not the fastest way to do this but its acceptable. i'm just having trouble with adjusting the algorithm to double link lists from arrays. My double linked lists have a type int and a type string to hold a number and a word. My list was sorted with an insertion sort that I wrote to sort alphabetically, now I need to reorder my double linked list numerically, greatest to least. My trouble spot is how to run this loop so that it is properly sorted thoroughly and

问题 After taking the summer off from C programming, I'm back in the thick of it for classes and am trying to catch up, particularly in pointers. The current assignment has us converting a program from an array structure to a simple linked list. In order to refresh my memory, I've tried implementing it in a standalone program, but am running into trouble. My code: struct node{ int val; struct node *next; }; typedef struct node *item; item newNode(void); //function prototype void main(){ item *cur,

问题 I am attempting to write a subList method, which returns a list consisting of the current object list inclusively between indexes fromIndex and toIndex . For example, if I had list consisting of 3 5 7 9 11 20 23 and I called subList(0,3) , I should get a new list of 3 5 7 9 returned. I am using helper methods to assist in writing the method. My logic in writing this method is that I assign the head node to to be the node at index fromIndex while assigning the last node in the list to the node

问题 I am trying to write a database for class in which I read all the key values in from a file (formatted keyNULL BYTEvalueNULL BYTE etc). I amt rying to use a linked list for this, but I get the error that the struct has no next value. Please help me! #include <stdio.h> #include <stdlib.h> #include <assert.h> #include <string.h> #include <stdbool.h> #include "sdbm.h" static FILE *db; static bool opened = false; static int err = 0, keyLen = 8; typedef struct { char *name; Key *next; } Key;

问题 I'm doing a program about doubly linked list. I have function find that helps locate, if per se, no. 7 is anywhere within that list. This function works fine and returns pointer to that node. Then I have function afterElement that inserts for example no. 3 after no. 7, So it uses pointer to find function as parameter. I think this is where the problem stems from, but I might be wrong, you be the judge. I wanna know, how can I correctly use this function? Is there something wrong with how I

问题 I looked at other posts and didnt find a great solution for my inquiry. I don't want to actually sort the linked list I want to see if its sorted or not. I have a linked list question in c++. I am asked to code a function given a linked list definition to see if its sorted. Implement the function isSorted – it returns true if the values in the linked list are sorted in increasing order. (The linked list is composed of integers). given the following sturct: struct ListNode { double value; //

问题 I'm trying to make a circular singly linked list. I'd like to be able to modify my code for a singly liked list but I'm have some trouble. For my linked list I have: class Link (object): def __init__ (self, data, next = None): self.data = data self.next = next class LinkedList(object): def __init__(self): self.first = None def __str__(self): a = "[" current = self.first while current != None: a += str(current.data) + ', ' current = current.next a = a[:-2] + ']' return a def __iter__(self):

问题 Does anyone have an example of a very simple implementation of a Circular Linked list using C#? I have this linked list but i dont know how to makeit cicular: public class LinkedList { public class Node { public Node next; public Object data; } private Node head; public void Add(Object data) { Node toAdd = new Node(); toAdd.data = data; Node current = head; current.next = toAdd; } } Thanks. 回答1: For your linked list to be circular, your tail node should reference the head node. So it's just a
