641. 设计循环双端队列 - 设计实现双端队列。 实现 MyCircularDeque 类: * MyCircularDeque(int k) :构造函数,双端队列最大为 k 。 * boolean insertFront():将一个元素添加到双端队列头部。 如果操作成功返回 true ,否则返回 false 。 * boolean insertLast() :将
Design your implementation of the circular double-ended queue (deque). Your implementation should support following operations: MyCircularDeque(k): Constructor, set the size of the deque to be k. insertFront(): Adds an item at the front of Deque. Return true if the operation is successful. ...
题干: https://leetcode.com/problems/design-circular-deque/ 这题跟622类似,算是它的进阶版,要支持双向的queue,大部分代码我都复用622的方案, 唯独要注意的一点是deleteLast和deleteFront要注意边界条件,就是当删完之后队列为空时,不要移动currentHead或者currentTail指针位置。 代码如下:...64...
