sequences are created with the help of the ‘seq’ command. following is a simple example of a sequence creation.
(ns clojure.examples.example (:gen-class)) ;; this program displays hello world (defn example [] (println (seq [1 2 3]))) (example)
the above program produces the following output.
(1 2 3)
following are the various methods available for sequences.
