Welcome to the Baklava in Erlang page! Here, you'll find the source code for this program as well as a description of how the program works.
-module(baklava).
-export([start/1]).
-spec start(MaxWidth :: integer()) -> ok.
start(MaxWidth) ->
baklava(MaxWidth, 0),
ok.
-spec baklava(MaxWidth :: integer(),
Incrementor :: integer()) -> ok.
%%--------------------------------------------------------------------
%% Recursively prints the top half of the baklava

baklava(MaxWidth, MaxWidth) ->
print((MaxWidth*2)+1, star),
reverse_baklava(MaxWidth, MaxWidth-1);
baklava(MaxWidth, Incrementor) ->
print(MaxWidth-Incrementor, space),
print((Incrementor*2)+1, star),
baklava(MaxWidth, Incrementor+1).
-spec reverse_baklava(MaxWidth :: integer(),
Decrementor :: integer()) -> ok.
