recur takes positional arguments, not (key value) "pairs" (which aren't pairs, but function calls). You want *something* like (recur (first end) (rest end) (contains? (get map start) value)) but I can't really make heads or tails out of your code. Note that '(56789) is a list of ONE number, while it looks like you're expecting it to be a list of digits - that would be '(5 6 7 8 9) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
