其实容器类就是一个有各种容器的接口，通过C++继承与多态的特性，能够自由的往容器类中添加各种数据结构。上图就是这个容器类的基本结构。其中带箭头的线表示继承关系、带矩形的线表示组成关系、带圆形的线表示这个类是一个纯虚类（可以理解成接口）为了编码的便捷，在下面的编码中我并没有自己写排序的算法，而是调用了algorithm 中的std::sort()函数.Collection.hpp// Created

描述A string S of lowercase letters is given. We want to partition this string into as many parts as possible so that each letter appears in at most one part, and return a list of integers representin

描述Say you have an array for which the ith element is the price of a given stock on day i.Design an algorithm to find the maximum profit. You may complete as many transactions as you like (ie, buy

描述Say you have an array for which the ith element is the price of a given stock on day i.Design an algorithm to find the maximum profit. You may complete at most k transactions.Note: You may no

描述Say you have an array for which the ith element is the price of a given stock on day i.Design an algorithm to find the maximum profit. You may complete at most two transactions.Note: You may

描述Say you have an array for which the ith element is the price of a given stock on day i.Design an algorithm to find the maximum profit. You may complete as many transactions as you like (ie, buy

描述Say you have an array for which the ith element is the price of a given stock on day i.If you were only permitted to complete at most one transaction (ie, buy one and sell one share of the stock

描述Your are given an array of integers prices, for which the i-th element is the price of a given stock on day i; and a non-negative integer fee representing a transaction fee.You may complete as many t

描述Given two strings s1, s2, find the lowest ASCII sum of deleted characters to make two strings equal.Example 1: Input: s1 = “sea”, s2 = “eat” Output: 231 Explanation: Deleting “s” from “sea” adds t

描述Given two integer arrays A and B, return the maximum length of an subarray that appears in both arrays.Example 1: Input: A: [1,2,3,2,1] B: [3,2,1,4,7] Output: 3 Explanation: The repeated subar

描述In this problem, a tree is an undirected graph that is connected and has no cycles.The given input is a graph that started as a tree with N nodes (with distinct values 1, 2, …, N), with one additiona

描述In this problem, a rooted tree is a directed graph such that, there is exactly one node (the root) for which all other nodes are descendants of this node, plus every node has exactly one parent, exce

近来在做概率统计的作业，由于手算均值中值什么的，还有画茎叶图太麻烦，所以写了个小程序。但是当我算到最后时却发现这个小程序有一个bug，然后就gg了。这个bug大概是这样的： 原本在data.txt中只有三个数，读到内存中却有四个数。 正确的结果应该是这样：出事的代码如下：#include <iostream>#include <fstream>#include <vector>#inclu

转载自：http://c.biancheng.net/cpp/biancheng/view/222.html> 用转换构造函数可以将一个指定类型的数据转换为类的对象。但是不能反过来将一个类的对象转换为一个其他类型的数据(例如将一个Complex类对象转换成double类型数据)。C++提供类型转换函数(type conversion function)来解决这个问题。类型转换函数的作用是将一个类的

C++ 继承 语法 程序设计 软件工程若有理解不当，欢迎各位指正！作者：吴博文 中山大学数据科学与计算机学院 本人博客：http://blog.youkuaiyun.com/bowen_wu_一、继承基本概念通过继承，所构建的新的类是基于可靠的基类(base class)，所以通过这种机制，可以提高代码的复用率（reuseability），从而减少新类的调试的工作量，从而提高编码的效率。同时，由于存在继承这个

题目Show that the following problem is NP-complete. MAXIMUM COMMON SUBGRAPH Input: Two graphs G1 = (V1, E1) and G2 = (V2, E2); a budget b. Output: Two set of nodes V1′ ⊆ V1 and V2′ ⊆ V2 whose delet
