Here's my take on it (all caveats apply, e.g. performance): (defn indices-of "Returns the indices of the given char in the string (0 based)." [c string] (map second (filter #(= c (first %)) (partition 2 (interleave string (iterate inc 0))))))
(indices-of \a "abba") ; (0 3) and hence last-index-of becomes: (def last-index-of (comp last indices-of)) (last-index-of \a "abbaa") ; 4 U -- You received this message because you are subscribed to the Google Groups "Clojure" group.
