问题 I am wondering what is the time complexity [in big O(n) notations] of ArrayList to Array conversion: ArrayList assetTradingList = new ArrayList(); assetTradingList.add("Stocks trading"); assetTradingList.add("futures and option trading"); assetTradingList.add("electronic trading"); assetTradingList.add("forex trading"); assetTradingList.add("gold trading"); assetTradingList.add("fixed income bond trading"); String [] assetTradingArray = new String[assetTradingList.size()]; assetTradingArray

问题 In my code I have a std::unordered_set and I need to move the data into a std::vector . I'm using the std::unordered_set while getting the data to ensure only unique values are stored prior to converting to a std::vector . My question is how do I move the contents to the std::vector the most efficiently? I don't need the std::unordered_set after the data is moved. I currently have the following: std::copy(set.begin(), set.end(), std::back_inserter(vector)); 回答1: Before C++17, the best you can

问题 Hi my name is Oscar and I would like some help! So the scenario I have is that I am trying to write a python code that will copy itself and put that copy in another directory. I know that you can use the shutil command. For example: import shutil shutil.copy("C:\Users\%user%\Downloads\file.txt", "C:\Users\%user%\Documents") But I want to just copy the file so that the script works on any computer that it is located on, for example: import shutil shutil.copy("file.txt", "C:\Users\%user%

问题 I am trying to copy a video file which has a size of 5Gbs. I use this simple line: copy($in, $out); But somehow the copied file has only a size of ~700 Mb. Is there a limit which the copy function has. Are there some other ways to copy files using php? 回答1: Ok I think I found a solution, I did following: exec('copy ' $in . ' ' . $out); This copied the whole file properly. I am not sure why exactly this works. My wild guess would be that copy() copies files immediately even if there a some

问题 A simple thing as I thought at first seems to be harder than I thought. I want to copy a vector of vectors of type int inside a copy constructor. std::vector<std::vector<int> * > * bar; I tried this but it is not working: Foo(const Foo& rhs) : bar(new std::vector<std::vector<int> * >(rhs.vec->size())) { for (std::size_t i = 0; i < rhs.bar->size(); i++) { bar->push_back(new std::vector<int>()); for (size_t j = 0; j < (*rhs.bar)[i]->size(); j++) { bar->back()->push_back((*rhs.bar)[i]->at(j)); }
