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 element in circular queue . In linear queue we can insert elements till the size of the queue is not fully occupied after that...
The complexity of the enqueue and dequeue operations of a circular queue is O(1) for (array implementations). Applications of Circular Queue CPU scheduling Memory management Traffic Management Previous Tutorial: Types of Queue Next Tutorial: Priority Queue Share on: Did you find this article ...
circular queue, dequeue(double ended queue) and priority queue. Queue can be implemented by using array and linked list. Suppose a linear queue is implemented by using array. We know that declaring an array is a static memory allocation. It means if we declare an array of 10 size to ...
Suppose that an array of size m is used to store a circular queue. If the head pointer front and the current size variable size are used to represent the range of the queue instead of front and rear, then the maximum capacity of this queue can be: A.m-1B.mC.m+1D.cannot be determ...
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 ...
定义队列(queue),是先进先出(FIFO, First-In-First-Out)的线性表。队列的操作方式和堆栈类似,唯一的区别在于队列只允许新数据在后端进行添加。 在具体应用中通常用链表或者数组来实现。队列只允许在后端(称为rear)进行插入操作,在前端(称为front)进行删除操作。进行插入操作的端称为队尾,进行删除操作的端称为队头...

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...
