A bounded queue is a queue limited to a fixed number of items. [1] There are several efficient implementations of FIFO queues. An efficient implementation is one that can perform the operations—en-queuing and de-queuing—in O(1) time. Linked list. A doubly linked list has O(1) insertion and deletion at both ends, so it is a natural choice ...
A doubly linked list whose nodes contain three fields: an integer value, the link forward to the next node, and the link backward to the previous node. A technique known as XOR-linking allows a doubly linked list to be implemented using a single link field in each node. However, this technique requires the ability to do bit operations on ...
A double-ended queue is represented as a sextuple (len_front, front, tail_front, len_rear, rear, tail_rear) where front is a linked list which contains the front of the queue of length len_front. Similarly, rear is a linked list which represents the reverse of the rear of the queue, of length len_rear.
It can be straightforwardly translated into e.g. Prolog which is not a lazy language. What is essential is the ability to build a list (used as the queue) in the top-down manner. For that, Prolog has tail recursion modulo cons (i.e. open ended lists). Which is also emulatable in Scheme, C, etc. using linked lists with mutable tail sentinel pointer:
A non-blocking linked list is an example of non-blocking data structures designed to implement a linked list in shared memory using synchronization primitives: Compare-and-swap; Fetch-and-add; Load-link/store-conditional; Several strategies for implementing non-blocking lists have been suggested.
Linked list can be singly, doubly or multiply linked and can either be linear or circular. Basic properties. Objects, called nodes, are linked in a linear sequence. A reference to the first node of the list is always kept. This is called the 'head' or 'front'. [3]
While priority queues are often implemented using heaps, they are conceptually distinct from heaps. A priority queue is an abstract data type like a list or a map; just as a list can be implemented with a linked list or with an array, a priority queue can be implemented with a heap or another method such as an ordered array.
