  ; to create a board of size n x n
> ; fill each position with indices i and j with (f i j)
> (define build-board
>  (lambda (n f)
>    (build-vector n
>                  (lambda(j)
>                      (build-vector n
>                                    (lambda (i)
>                                      (f i j)))))))
