I am reading The Joy of Clojure now and am finishing chapter 5 on sequence abstractions. There is an example given that demonstrates how to locate the index of an element in a sequence by value, but I don't understand why the character lookup here is returning 13. Can somebody please explain this to me?
(defn index [coll] > (cond > (map? coll) (seq coll) > (set? coll) (map vector coll coll) > :else (map vector (iterate inc 0) coll))) > > (defn pos [pred coll] > (for [[i v] (index coll) :when (pred v)] i)) > > (pos \3 ":a 4 :b 1 :c 3 :d 4") => 13 J -- You received this message because you are subscribed to the Google Groups "Clojure" group.
