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 ...
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...
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...

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...
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 ...

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...
