I insert all string that show up in the map into index (std::map<string,int> index).
And I use these code to debug:
string s1,s2;
cin >> s1 >> s2;
if (index.find(s1) == index.end() || index.find(s2) == index.end())
    while (true);//if the string doesn't show up in the map,I will get TLE.
...
And I got TLE #2.
Who can help me?
Thanks.
Sorry for my poor English.
PS:It's guarantee that I won't insert wrong string into index.
