For USACO, which array would you recommend using? I think STL is better because you can pass it into functions, but I see many USACO Platinum contestants use the standard array. Which one should I use? Thanks!
Do you mean a vector vs an array? If that is the case, then I’d say to use a vector because it has more built-in functions as well as the feature to add and remove elements 
.
Yeah, that was what I was talking about. Thanks for your help!
