Circular queue avoids the wastage of space in a regular queue implementation using arrays. In this tutorial, you will understand circular queue data structure and it's implementations in Python, Java, C, and C++.
//C Program #include <stdio.h> #define SIZE 5 int items[SIZE]; int front = -1, rear =-1; // Check if the queue is full int isFull() { if( (front == rear + 1) || (front == 0 && rear == SIZE-1)) return 1; return 0; } // Check if the queue is empty int isEm...
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. 0x03 循环队列的实现 In[10]:defenqueue(item):...:# queue 为空/一直插入元素到没有...
Die Queue wird auch als First-In, First-Out (FIFO)-Datenstruktur bezeichnet, wobei die Reihenfolge berücksichtigt wird, in der Elemente aus einer Queue kommen, dh das erste Element, das in die Queue eingefügt wird, ist das erste, das entfernt wird. Es folgt eine einfache Darstellung e...
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...

Many DSPs as well as data converters such as ADCs implement a FIFO queue as a circular buffer (Figure 5.29). Circular buffers realize the delay line in a filter operation, for example, by moving a pointer through the data instead of moving the data itself. The new data sample is written...
