1. Enqueue Operation check if the queue is full for the first element, set value ofFRONTto 0 circularly increase theREARindex by 1 (i.e. if the rear reaches the end, next it would be at the start of the queue) add the new element in the position pointed to byREAR ...
LeetCode 622:设计循环队列 Design Circular Queue 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... 69330 Circular buffer 大家好,又见面了,我是全栈君 前言: A circular buffer, cyclic buffer or ring buffer is a...
Queue can be one linear data structure. But it may create some problem if we implement queue using array. Sometimes by using some consecutive insert and delete operation, the front and rear position will change. In that moment, it will look like the queue has no space to insert elements ...
Front: Get the front item from the queue. If the queue is empty, return -1. Rear: Get the last item from the queue. If the queue is empty, return -1. enQueue(value): Insert an element into the circular queue. Return true if the operation is successful. deQueue(): Delete an elemen...

Record last operation. Always Keep One Slot Open [最简单有效的解决的方法就是保持最后一个单元不写] This design always keeps one slot unallocated. A full buffer has at most slots. If both pointers refer to the same slot, the buffer is empty. If the end (write) pointer refers to the slot...
