3 Python 答题 ## LeetCode 622M Design Circular Queue class MyCircularQueue: def __init__(self, k: int): self.data = [0]*k ## 初始化 - 全部元素为0 self.size = k self.headIndex = 0 self.count = 0 ## 初始化队列为空 def enQueue(self, value: int) -> bool: ## 考虑如果队列...
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 ...
The most common queue implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Circular Queue implementation in Python class MyCircularQueue(): def __init__(self, k): self.k = k self.queue = [None] * k self.head = self.tail = -1 # Insert...
One of the Benefits of the circular queue is that we can make use of the spaces in front of the queue. In a normal queue, once the queue becomes full, we can not insert the next element even if there is a space in front of the queue. But using the circular queue, we can use ...

It’s also known with alternative names such as a circular queue or ring buffer, but we will refer to it as a circular array throughout this article. The circular array has FIFO (First In, First Out) mechanism for element insertion and removal operations. Usually, the buffer will have a...
python报错: AttributeError: partially initialized module 'json' has no attribute 'dump' (most likely due to a circular import) 这是由于我的py文件名字是json.py,导致import json导入的是我自己写的py文件而不是python库。 解决办法当然就是把文件名改掉... ...
队列(Queue)是只允许在一端进行插入,而在另一端进行删除的运算受限的线性表 (1)允许删除的一端称为队头(Front)。 (2)允许插入的一端称为队尾(Rear)。 (3)当队列中没有元素时称为空队列。 (4)队列亦称作先进先出(First In First Out)的线性表,简称为FIFO表。 队列的修改是依先进先出的原则进行的。新...
