Add weights to the elements of the queue and use an algorithm to sort the queue every time an element is added.
I'm sorry brother
A singly-linked circular list is useful for implementing queue data structures with minimum overhead. Normally we implement a queue with two pointers: one to the tail for insertions and one to the head for extractions. With a circular list we only need to maintain a single pointer to the tail because the tail always points "forwards" to the head (instead of null as it normally would), thus achieving constant-time access to both the head and tail via a single pointer. Circular linked lists are generally useful wherever "wraparound" is necessary. That is, from any given node in the list, we can traverse forwards with the guarantee that we will eventually arrive back at that same node. With doubly-linked circular lists we have the advantage of traversing in either direction (bi-directional traversal).
Create a new node, making sure it is not allocated locally in the function and thus will not be destroyed when the function execution finishesFill in dataUse the "last node" pointer in the list and copy the "next" pointer location (pointing to the first node) into the new nodes "next" pointerSet the "last node" "next" pointer to point to the new nodeChange the list's "last node" pointer to point to the new nodeFor an example of implementation see: How_you_insert_a_newnode_in_singly_circular_link_list
Yes, each node in a doubly linked list contain a link to the previous as well as the next node. That is the definition of the doubly linked list.
store the exor of the previous node address and next node address in each node of single linked list .further exor the nodes to proceed forward or backward as necessary
You'll need to use a doubly-linked circular list, since otherwise when you pop off the tail element you'll need to whizz all the way round the list to find its predecessor. See the links section for an implementation of a doubly-linked circular list.
I'm sorry brother
A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.
Use the word 'doubly' in a sentence:All these questions are hard, but this one was doubly hard.
Yes. The tail node's next node is the head node, while the head node's previous node is the tail node.
if (this->next) this->next->prev= this->prev; else list->last= this->prev; if (this->prev) this->prev->next= this->next; else list->first= this->next; free (this);

A number is even if it is divisible by 2. It is doubly even if it is divisible by 4.
The leaf labeled "C" in the illustration is a doubly compound leaf.
Add another pointer to the nodes for the previous node: struct node { struct node *next; struct node *previous; void *data; }; typedef struct node node; Then change the logic for insertion and removal to make sure you set the previous pointer as well as the next one.
