Question to people who've been to IOI (C++ STL policy based DS)
By khokho, history, 7 years ago, In English

Hey guys, I just found out about policy based data structures implemented in C++ STL (here), is it allowed/possible to use them on IOI?

(I understand that will highly probably won't need it on IOI because of style of problems, but still...)

Yes, it is allowed to use them if the C++ compiler in the contest supports them, and most probably it will. It's a good idea to test this during the practice session if you consider using them.

Another similar question:

Is it allowed to use "#pragma GCC optimize("O3")" ?

    Sure, you can use all features that the compiler provides.

    The IOI rules specify what is not allowed. You can't use files, network etc., but otherwise there are no restrictions.

    You won't need it, your solutions anyway are trash.
