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.k = k self.queue = [None] * k self.head = self.tail =-1# Insert an element...
存储在其中的队列称为循环队列(Circular Queue)。 条件处理 循环队列中,由于入队时尾指针向前追赶头指针;出队时头指针向前追赶尾指针,造成队空和队满时头尾指针均相等。因此,无法通过条件front==rear来判别队列是"空"还是"满"。 解决这个问题的方法至少有三种: ① 另设一布尔变量以区别队列的空和满; ② 另...
Assuming that the elements of the circular queue are stored in the array A[m], and the head and tail pointers are front and rear respectively, the number of elements in the current queue is ( ).A.A (rear-front+m)%mB.B rear-front+1C.C (front-rear+m)%mD.D (rear-front+1)%m...

(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...
In one embodiment, a method includes receiving, by a kernel of an operating system executing on a computing device, a request to store a message to communicate from a first process to a second process using a circular buffer. The circular buffer includes a first number of memory segments. ...
