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"...
MyCircularQueue circularQueue = new MycircularQueue(3); // 设置长度为 3 circularQueue.enQueue(1); // 返回 true circularQueue.enQueue(2); // 返回 true circularQueue.enQueue(3); // 返回 true circularQueue.enQueue(4); // 返回 false,队列已满 circularQueue.Rear(); // 返回 3 circularQueue...
MyCircularQueue(k) Initializes the object with the size of the queue to be k. 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 ...
