int Front() Gets the front item from the queue. If the queue is empty, return -1. int Rear() Gets the last item from the queue. If the queue is empty, return -1. boolean enQueue(int value) Inserts an element into the circular queue. Return true if the operation is successful. boo...
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"...

LeetCode 622:设计循环队列 Design Circular Queue 首先来看看队列这种数据结构: 队列:先入先出的数据结构 在FIFO数据结构中,将首先处理添加到队列中的第一个元素。 如上图所示,队列是典型的 FIFO 数据结构。插入(insert)操作也称作入队(enqueue),新元素始终被添加在队列的末尾。 删除(delete)操作也被称为出队(de...
enQueue(value): Insert an element into the circular queue. Return true if the operation is successful. deQueue(): Delete an element from the circular queue. Return true if the operation is successful. isEmpty(): Checks whether the circular queue is empty or not. ...
