(take 5 (repeat "x")) ("x" "x" "x" "x" "x") ;; which is the same as: (repeat 5 "x") ("x" "x" "x" "x" "x") ;; It should be noted that repeat simply repeats the value n number of times. ;; If you wish to execute a function to calculate the value each time you ;; probably want the repeatedly function. (take 5 (repeat (rand-int 10))) (1 1 1 1 1) (take 5 (repeat (rand-int 10))) (6 6 6 6 6) (take 5 (repeat (rand-int 10))) (0 0 0 0 0) ;; etc.

(defn tally [n] (apply str (concat (repeat (quot n 5) "卌") (repeat (mod n 5) "|")))) (map tally (range 1 11)) ;; ("|" "||" "|||" "||||" "卌" "卌|" "卌||" "卌|||" "卌||||" "卌卌")
