c++ - Should I randomly shuffle before inserting into STL set? -


I need to insert 10 million strings into a C + + STL set. I string is sorted if I sort order Do I have a disease problem? Should I Make Random First? Or will the implementation of G + STL be reborn automatically for me?

I have only one question: do you really need a set ?

If the data is already sorted and you do not need to insert / delete elements after creation, then a deck will be better

  • You will have only one big-o complexity to retrieve
  • You will get less memory overhead ... and better cache terrain

at Binary_search : I suspect that you need more than ForwardIterator for a binary search, guess that this site is again Area is closed: (

But I do not think the code is capable of changing the color of each variable declared....
