[erlang-questions] create list quesion

[Roelof Wobben]

Hello,

Oke,

Something like this in pseudo code :

create(0) ->
print empty array

create(x) ->
   create_array(x, []) )

create_array(0, array) ->
  print array

create_array(x, array) ->
   add the first item to the array and run create_array again
