-export([maxThree/3, howManyEqual/3]).

maxThree(X,Y,Z) ->
  case lists:sort([X,Y,Z]) of
    [_,_,M] -> M;
    _ -> 0
  end.

howManyEqual(X, X, X) -> 3;
howManyEqual(X, X, _) -> 2;
howManyEqual(_, X, X) -> 2;
howManyEqual(X, _, X) -> 2;
howManyEqual(_, _, _) -> 0.

Good solution, but using lists:sort/1 is cheating ;)

Is there a real difference, though? Does 'lists/sort/1' put things in a different order than using max()? I.e. is one numerical/binary while the other is ???

no, no... The code is fine. It's just that the course did not go over list functions yet ;)

@elbrujohalcon @EarlOfBDE the reason I used lists:sort/1 instead of max is because I wanted to do pattern matching here. :)
