Enque and Deque Operations Circular Queue Implementations in Python, Java, C, and C++ The most common queue implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Circular Queue implementation in PythonclassMyCircularQueue():def__init__(self, k):self...
Your implementation should support following operations: MyCircularQueue(k): Constructor, set the size of the queue to be k. Front: Get the front item from the queue. If the queue is empty, return -1. Rear: Get the last item from the queue. If the queue is empty, return -1. enQueue...
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. ...
Circular buffering makes a good implementation strategy for aqueuethat hasfixed maximum size. Should a maximum size be adopted [被採用]for a queue, then a circular buffer is a completely ideal implementation; all queue operations are constant time. However, expanding a circular buffer requires shif...
(This class is roughly equivalent to ArrayList, except that it is optimized for removing elements at the front and back of the list to facilitate use as a queue or deque. The size, isEmpty, get, set, iterator, and listIterator operations run in constant time. The add op...
