Re: arrays vs. vectors

In Scheme, since the purpose is to teach you how to implement stuff,

Let me make sure I understand this correctly. If I want to implement
something in Scheme based on nested for loops with i,j notation, I have
to go though all of what you did above?


It is easier to usean existing library:
