deque的左边(left)就相当于它的队列头(front)、右边(right)就相当于它的队列尾(rear)。 append和appendleft:在deque的右边或左边添加元素;也就是默认在队列尾添加元素。 pop和popleft:在deque的右边或左边弹出元素;也就是默认在队列尾弹出元素。 extend和extendleft:在deque的右边或左边添加多元素;也就是默认在队列...
C++代码实现: intdeQueue(){intelement;if(isEmpty()){cout<<"Queue is empty"<<endl;return(-1);}else{element=items[front];if(front==rear){front=-1;rear=-1;}else{front=(front+1)%SIZE;}return(element);}} Demo4.完整代码实现 Python代码实现: classCircularQueue():def__init__(self,k):...
So, to access __honey attribute in the first snippet, we had to append _Yo to the front, which would prevent conflicts with the same name attribute defined in any other class. But then why didn't it work in the second snippet? Because name mangling excludes the names ending with double...
(rear + 1) % maxSize == front(队尾继续往前移动一个单位就可以和队头汇合) Demo1.初始化 初始化时,顺序队列和循环队列的代码表示方式是一样的。主要初始化数组的大小、队头和队尾的初始值。 Python代码实现: 代码语言:javascript 复制 classCircularQueue():def__init__(self,k):self.k=k ...
