Hi, I'm trying to wrap my head around functional programming, and I'm
having some trouble doing the following:
Here's a small iterator function that I wrote, which calls a function
on each element of a vector-of-vectors.
(defn v2d-each
([v2d stRow endRow stCol endCol func]
(doseq r (range (max 0 stRow) (min (v2d :rows) endRow))
(doseq c (range (max 0 stCol) (min (v2d :cols) endCol))
(func r c (v2d-get v2d r c)))))
But this function turned out to be not as useful as I had hoped,
because there's no way for me to early exit the iterator (as Clojure
doesn't have Ruby's break or return statements)
Could I have some help writing this in idomatic Clojure?
Thank you very much
-Patrick
