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 -...
Design your implementation of the circular queue. The circular queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle and the last position is connected back to the first position to make a circle. It is also called "Ring Buffer"...

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(): Adds an item at the front of Deque. Return true if the operation is successful.insert...
Claudio presents a C++ template implementation of a bounded buffer as a circular queue, then shows how to make the circular queue compatible with STL algorithms.
In this article, I present a C++ template implementation of a bounded buffer as a circular queue. I also show how to make, the circular queue compatible with STL algorithms by providing a special iterator used as an interface between the algorithms and the circular queue. The bounded buffer ...

Es gibt mehrere effiziente Implementierungen von FIFO-Queuen. Eine (begrenzte) Queue kann einfach mithilfe eines Arrays mit einer Struktur aus fünf Elementen implementiert werden: structure stack: item : array maxsize : integer front : integer ...
