Demonstrate in your programming language the following: |
|||
1. Construct a Monad (preferably the Option/Maybe Monad) |
|||
2. Make two functions, each which take a number and return a wrapped number |
|||
3. Compose the two functions with bind |
|||
=={{header|Clojure}}== |
|||
List Monad: |
|||
<lang clojure> |
|||
(defn bind [coll f] (apply vector (mapcat f coll))) |
|||
(defn unit [e] (vector e)) |
|||
(def vecstr (comp vector str)) |
|||
(defn doubler [n] [n n]) |
|||
(bind (bind [3 4 5] vecstr) doubler) ; evaluates to ["3" "3" "4" "4" "5" "5"] |
|||
(-> [3 4 5] |
|||
(bind vecstr) |
|||
(bind doubler)) ; also evaluates to ["3" "3" "4" "4" "5" "5"] |
