[plt-scheme] Re: create a board with vector

The problem I have here is that I cant underestand what is happening

                        (build-vector n
	                   	                 (lambda (i)
                                   			   (f i j)))))))

build_vctor has 2 inputs, it seems one of the inputs is n and the
other is (lamda (i) (f i j)). I cant understand what (lamda (i) (f i
j))   will produce.
