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...
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...

Circular Queue The difficulty of managing front and rear in an array-based non-circular queue can be overcome if we treat the queue position with index 0 as if it comes after the last position (in our case, index 9), i.e., we treat the queue as circular. Note that we use the ...
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...
(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...
It’s also known with alternative names such as a circular queue or ring buffer, but we will refer to it as a circular array throughout this article. The circular array has FIFO (First In, First Out) mechanism for element insertion and removal operations. Usually, the buffer will have a...
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...
