利用数组 Q[1..n] 来实现含有 n-1 个元素队列(保留一位元素用来判断队列空或满)。该列有一个属性 Q.head 指向队头元素,属性 Q.tail 指向下一个新元素将要插入的位置,列中的元素存放在位置 Q.head, Q.head+1, …, Q.tail-1 上。 初始时,Q.head = Q.tail = 1 当Q.head = Q.tail 时, 队列...
As shown below, you can implement the entire logic in the printList() method. class Node: def __init__(self, data): self.data = data self.next = None class LinkedList: def __init__(self): self.Head = None def printList(self): current = self.Head while current is not None: ...

Head Frist Python 读书笔记 列表推导(list comprehension) 列表推导(list comprehension)是个挺有意思的功能,应该是一个语法糖吧,列表推导这个名字大概是意译,不过list comprehension这个真不知道该怎么翻译。 列表推导是Python支持函数编程概念的一个例子。 列表推导的功能是减少代码书写量,可以省点事情,本来需要两行的,...

数组是一种特殊的对象,用于存储一系列的值。清空数组意味着移除数组中的所有元素。 二、相关优势 高效性:某些方法可以在常数时间内完成清空操作。 简洁性:代码简短,易于理解和维护。 三、类型及方法 设置长度为0 设置长度为0 这种方法直接修改数组的长度属性,从而清空数组。它的优势在于速度快,且能保留原数组的引用...
