cin.tie() doesn't do anything useful in your code(it returns a pointer to cout).
cin.tie(0) gives a massive speed increase as it means reading from cin doesn't flush cout.

Sorry, but why is that ?
cin.tie() unties Cin and Cout. But I agree that cout.tie() is useless there.
Without arguments it doesn't change anything (it returns a pointer to the currently tied output stream). You need to pass nullptr/0 to untie the streams.
