I want to get first N (for example 100) unique random floats. Here is
what I have.
(defn rand-flt [max-flt]
(format "%.2f" (rand max-flt)))
(defn gen-rand-flts [max-flt]
(lazy-seq (cons (rand-flt max-flt) (gen-rand-flts max-flt))))
(defn get-n-floats [max-float, how-many]
(let [tf-fun (fn [] (take how-many (gen-rand-flts max-float)))]
(loop [sof (set (tf-fun))]
(if (> (count sof) (dec how-many))
(take how-many sof)
(recur (set (concat sof (tf-fun))))))))
(get-n-floats 100.0 10)
This works but I feel that should be more idiomatic solution for get-n-
floats. I have tried take-while, some, even read about delay/force but
couldn't come up with a shorter alternative; main problem is realizing
lazy seq. Any suggestions?
