思路很简单，写博客目的是记住find、substr的用法

#include<iostream>#include<set>using namespace std;int main(){    set<string> s;    string temp;    while (cin >> temp)    {        s.insert(temp);    }    for (set<string>::iterator it = s.begin(); it != s.end(); it++)    {        string a = *it;        for (int i = 1; i < a.length(); ++i)        {            if (s.find(a.substr(0, i)) != s.end() && s.find(a.substr(i, a.length() - i)) != s.end())//核心            {                cout << a << endl;                break;            }        }    }}
