Code explanation to implementation of priority queue using linked list In the Code below there are four parts. First three function to implement three different operations like Insert a node, delete a node and display the list. The Fourth part is the main function, in that a do while loop i...

Dequeue and Priority Queue in C - As we know that the queue data structure is First in First Out data structure. The queue has some variations also. These are the Dequeue and the Priority Queue.The Dequeue is basically double ended queue. So there are t

CBPQ: High Performance Lock-Free Priority Queue 463 Fig. 1. Overview of the CBPQ data structure When an internal chunk is filled due to insertions, it is split into two half- full chunks using the lock-free freezing mechanism of [3]. The CBPQ scheme is illustrated in Fig. 1 (with ...
In a queue, thefirst-in-first-out ruleis implemented whereas, in a priority queue, the values are removedon the basis of priority. The element with the highest priority is removed first. Implementation of Priority Queue Priority queue can be implemented using an array, a linked list, a heap...
