| Subject: | [Caml-list] Mapping onto lists |
Is there any way to combine these two functions(map and my_map) so
that the following will work?
let plus x y = x + y;;
let rec map f = function
[] -> []
| head::tail -> let r = f head in r :: map f tail;;
map (plus 2) [10; 100; 100];;
- : int list = [12; 102; 1002]
let rec my_map f = function
[] -> []
| head::tail -> let r = head f in r :: my_map f tail;;
my_map 10 [plus 2; plus 4; plus 7];;
- : int list = [12; 14; 17]
(* Combined mapping function *)
combined_map 2 [plus 10; plus 100; plus 1000];;
combined_map (plus 2) [10; 100; 100];;
