每小题10分，共30分）要求：理解并应用数据结构与算法的基本概念，完成以下题目。1. 使用Python实现一个栈（Stack）类，支持push、pop、peek和isEmpty方法。2. 编写一个函数，实现快速排序算法，对一个整数列表进行排序。3. 使用Python实现一个二叉搜索树（BST）类，包含插入、搜索和删除节点的方法。
科班出身的码畜一直被灌输一条上帝圣经:“一个int占4个字节,一个char占1个字节,一个float占4个字节。。。”, 今天看下了python的getsizeof函数,发现python中各个基本数据类型(对象)占用的内存大小和c++/Java完全不一样~ 前提概述:python中一切都是对象,so python中其实根本不存在int float这些类型,int其实是一个...
