Ok, stupid mistake again.
Basically, the last line will be always \n
So if you did something like this to read the input:
std::string s;
while(!std::cin.tie(0)){
     std::cin >> s;
}
The Program will read an empty string.
So you need to read as:
while(!std::cin.tie(0)){
     std::cin >> s;
     if(!s.size())break;
}
I got WA #6, So I thought my diagonal code was wrong! Lol.
