I want to know what to use while passing an array or vector by reference in a function. By referring to other people’s solutions, I found that some solutions had vector<int> &edges and some had vector<int> *edges. Also, some people use int vis[] or some use int &vis.
I want to know which is the best passing by reference technique ?
Expecting positive response from all of you.
Also, any good coding practices from you will be welcome. Thanks in advance.
