一:题目 给出一段英文,里面包含一些单词,空格和标点,单词不区分大小写,默认都为小写.按照字典序输出这些单词(这些单词不能有重复,字母全部变成小写) (一)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. (二)样例输出 a

题意:输入文本,把不同的单词按照字典序排列. /* tolower 功 能: 把字符转换成小写字母,非字母字符不做出处理 头文件 目前在头文件iostream中也可以使用 isalpha 一种函数:判断字符ch是否为英文字母,若为英文字母,返回1.若不是字母,返回0 stringstream,由iostream派生而来,提供读写string的功能. */ #include<iostream> #include<set> #include<sstream> #includ

感觉这道题要比之前几个字符串处理的题目难度要大了一些. 题目大意:给若干行字符串,提取出所有单词并去掉重复的,最后按字典顺序输出. 对于输入大致有两种思路,一种是逐个读入字符,遇到字母的话就放到word里面,直到遇到非字母字符,在word最后放'\0'. 我采用第二种思路,就是用gets()函数逐行读到str字符数组里面,然后逐个把单词提取出来. Count存放的是Dictionary里单词的个数,每提取一个单词,看看Dictionary里有没有该单词,没有的话放到字典里面,并且计数器加1. 由

[链接] 我是链接,点我呀:) [题意] 在这里输入题意 [题解] 用stringstream来处理中间的标点. ->直接把他变成一个空格. 然后重新输入进去. set默认的字典序就是升序的了. [错的次数] 在这里输入错的次数 [反思] 在这里输入反思 [代码] #include <bits/stdc++.h> using namespace std; set<string> myset; string s; int main() { //freopen("F:\

水题题目描述就不写了 主要是发现stringstream真的是好用,可以把string绑定到stringstream中,然后就能以空格为分隔符分割出每个单词,听说每次重新创建stringstream开销是巨大的,但是这题两种写法时间上并无太大差别 #include <iostream> #include <cstdio> #include <cstring> #include <sstream> #include <algorithm> #inc

#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 >&
