1.set 集合 哦....对了,set有自动按照字典序排序功能..... 声明和插入操作 #include <cstdio> #include <vector> #include <set> using namespace std; int main(){ vector<int> v; ; i < ; i++) { v.push_back(i); v.push_back(i); } set<int> s; s.insert(v.begin…

题目描述: #include<iostream> #include<string> #include<set> #include<sstream> using namespace std; set<string> dic; string s, buf; int main() { while(cin >> s) { ; i < s.length(); i++) if(isalpha(s[i])) s[i] = tolower(s[…

输入一个文本,找出所有不同的单词(连续的字母序列),按字典序从小到大输出.单 词不区分大小写. 样例输入: Adventures in Disneyland Two blondes were going to Disneyland when they came to a fork in the road. The sign read: "Disneyland Left." So they went home. 样例输出(为了节约篇幅只保留前5行): a adventures blond…

#include<bits/stdc++.h>using namespace std;set<string> dict;int main(){ string s, buf; while(cin >> s) { for(int i = 0;i < s.length();i++) { if(isalpha(s[i])) s[i] = tolower(s[i]); else s[i] = ' '; } stringstream ss(s); while(ss >&…

Andy 是个 8 岁的孩子,他梦想要制作一本他自己的字典. 这并不是一件容易的事,因为他认识的字还不是那么多. 他并不想要自己去想这本字典中该放哪些字,他有个聪明的主意. 就是拿出他最喜欢的一本故事书,从那里面挑出所有不同的字来,然后按照字典数序列出. 当然,对他来说这是一件相当花时间的工作,所以你被要求写一个程序来帮助他. 在这个问题中,一个字被定义为一连续字母所组成的字符串. 并且,你的程序应该是不管字母大小写的. 例如: "Apple", "apple",…

set就是数学上的集合——每个元素最多只出现一次,和sort一样,自定义类型也可以构造set,但同样必须定义“小于”运算符 以下代码测试set中无重复元素 #include<iostream> #include<iterator> #include<set> using namespace std; typedef long long LL; ]={,,}; int main() { set<LL>s; s.insert(); s.insert(); s.i…
