Design your implementation of the circular double-ended queue (deque). Your implementation should support following operations: MyCircularDeque(k): Constructor, set the size of the deque to be k. insertFront():
Implementation the MyCircularQueue class: MyCircularQueue(k) Initializes the object with the size of the queue to be k. int Front() Gets the front item from the queue. If the queue is empty, return -1. int Rear() Gets the last item from the queue. If the queue is empty, return -...

RingBuffer implements classic fixed length ring buffer (aka circular queue). For the ring buffer use case, RingBuffer is a drop in replacement for Array because push, pop, unshift, shift, and length match the signature of Array. For buffer operation either use push/shift or unshift/pop toget...

Should a maximum size be adopted for a queue, then a circular buffer is a completely ideal implementation; all queue operations are constant time. However, expanding a circular buffer requires shifting memory, which is comparatively costly. For arbitrarily expanding queues, a linked list approach ...
In a doubly linked list,tailthe next pointer of points tohead, andheadthe previous pointer of points totail, forming a doubly circular linked list. Why is it a cycle? Useful for implementing several data structures (e.g. queues, Fibonacci heaps). An efficient queue can be built withoutusin...
