I want to use vector<int> adj[] as my parameter and vector<vector<int>> as my return function type but doing that will cause an error : This happens when returning the vector adj. could not convert adj from std::vector<int>* to std::vector<std::vector<int> > return a...

std::vector<wchar_t> chars(word.begin(), word.end()); The above will not add the null terminator (but if the string contains one, it will be copied). If you want it, initialize the vector with a pair of pointers to the underlying string data instead: std::vector<wchar_t> chars...
