Post Robot
一、题目
DT is a big fan of digital products. He writes posts about technological products almost everyday in his blog.
But there is such few comments of his posts that he feels depressed all the day. As his best friend and an excellent programmer, DT asked you to help make his blog look more popular. He is so warm that you have no idea how to refuse. But you are unwilling to read all of his boring posts word by word. So you decided to write a script to comment below his posts automatically.
After observation, you found words “Apple” appear everywhere in his posts. After your counting, you concluded that “Apple”, “iPhone”, “iPod”, “iPad” are the most high-frequency words in his blog. Once one of these words were read by your smart script, it will make a comment “MAI MAI MAI!”, and go on reading the post.
In order to make it more funny, you, as a fan of Sony, also want to make some comments about Sony. So you want to add a new rule to the script: make a comment “SONY DAFA IS GOOD!” when “Sony” appears.

分析
字符串处理
遇到苹果的相关词汇输出MAI MAI MAI!,遇到Sony输出SONY DAFA IS GOOD!
考虑到输入顺序的问题,字符需要一个一个读入,不然输出顺序可能与输入的顺序不一致
#include<iostream>
using namespace std;
int main()
{string s;while(cin>>s){string s1;for(int i=0;i<s.size();i++){s1+=s[i];if(s1.find("Apple")!=-1||s1.find("iPad")!=-1||s1.find("iPhone")!=-1||s1.find("iPod")!=-1)cout<<"MAI MAI MAI!"<<endl,s1.erase(s1.size()-1,1);//输出后破坏被找到的字符串,这样在下一轮find的时候,这个单词就不会被找到if(s1.find("Sony")!=-1)cout<<"SONY DAFA IS GOOD!"<<endl,s1.erase(s1.size()-1,1);}}
}
