circular-list

问题 So my program has a need of a type of circular ArrayList. Only circular thing about it has to be the get(int index) method, this is the original: /** * Returns the element at the specified position in this list. * * @param index index of the element to return * @return the element at the specified position in this list * @throws IndexOutOfBoundsException {@inheritDoc} */ public E get(int index) { rangeCheck(index); return elementData(index); } If index is -1 it should get the element with

问题 I have data that is arranged in a ring structure (or circular buffer), that is it can be expressed as sequences that cycle: ...-1-2-3-4-5-1-2-3-.... See this picture to get an idea of a 5-part ring: I'd like to create a window query that can combine the lag and lead items into a three point array, but I can't figure it out. For example at part 1 of a 5-part ring, the lag/lead sequence is 5-1-2, or at part 4 is 3-4-5. Here is an example table of two rings with different numbers of parts

问题 I am writing a small strategic game, but I have a problem with implementing a circular linked list. The game involves several people taking actions one by one and round by round until the game ends. I though that this could be done by using a circular linked list where each element is a player with a reference to the next player. The structure is like this: #[derive(Debug, Clone)] struct Player { name: String, killed: bool, next: Option<Box<Player>>, } I also want a pointer to the current

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . We have been given homework from lisp where I need to use "cyclic" list (I don't know what is the right naming for this). By "cyclic" list, I mean list, where cdr of the last one cons points to the very first one

问题 I tried to implement circular linked list to manage a set of tasks by a server side application. The application is multi-threaded where one thread ( updater() ) reads the linked list only for read while another two ( push_stream() and delete_stream() ) access the linked list to add to and delete from the linked list respectively. My problem is not all the files to be deleted (after being processed) are deleted. struct data_stream { bool processed; int count; char filename[30]; int TYPE_GRP;

问题 I am done with insertion, search in circular linked list but for removal I am getting compiler errors... Following is my structure for nodes. struct node { int p_data; struct node* p_next; node(node* head, int data) { p_next = head; p_data = data; } explicit node(int data) { p_next = nullptr; p_data = data; } }; node* remove_circular(node* head, node* target) { if (head == target->p_next) { delete head; return nullptr; } auto next_pointer = target->p_next; target->p_data = next_pointer->p

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

问题 I'm trying to implement an replacement algorithm that deals with page faults. So i'm trying to creat a circular linked list using malloc and im getting the following error: "invalid application of sizeof' to incomplete type pageInMemory'.following is the code: typedef struct { int use; int reference; int free; struct pageInMemory* next; } pageInMemory; int main() { int i; struct pageInMemory* start, *nn, *temp, *hand; start = NULL; for(i=0; i< pNum; i++) { nn = (struct pageInMemory *)malloc
