Queue can be one linear data structure. But it may create some problem if we implement queue using array. Sometimes by using some consecutive insert and delete operation, the front and rear position will change. In that moment, it will look like the queue has no space to insert elements ...
In this Java tutorial, we are going to discuss the circular queue and its array implementation in java. What is Circular Queue? Circular Queue is a linear data structure in which operations are performed on FIFO ( First In First Out ) basis . Element at last position is connected to front...

//using a static array of size 100. }; Input None Output None Hint Submit your implementation only. 首先简单说明一下queue的用法: back()返回队列最后一个元素引用 empty()是检查是否为空的方法 front()获得队列最前面一个元素引用 push()在队列尾添加一个数据 ...
One of the benefits of the circular queue is that we can make use of the spaces in front of the queue. In a normal queue, once the queue becomes full, we cannot insert the next element even if there is a space in front of the queue. But using the circular queue, we can use the...
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...
题目 Suppose that an array of size m is used to store a circular queue. If the front position is front and the current size is size, then the rear element must be at A.front+sizeB.front+size-1C.(front+size)%mD.(front+size-1)%m 相关知识点: 试题来源: 解析 D 反馈 收藏 ...
Circular Buffer, Cyclic Buffer or Ring Buffer is a data structure that effectively manages a queue of some items. Items can be added at the back and removed from the front. It has limited capacity because it is based on preallocated array. Functionality is implemented using two pointers or in...
queue using anOutpointer, also not shared with the producer. TheOutpointer represents the position of the next element to be removed from a nonempty buffer. The queue is implemented as an array withCapacity=N+1, whereNrepresents the maximum number of items allowed in the queue andCapacityis ...
