M.3. program. Quicksort

quicksort([H|T]) ->


        {Smaller_Ones,Larger_Ones} = split(H,T,{[],[]}),
        lists:append( quicksort(Smaller_Ones),
        [H | quicksort(Larger_Ones)]
);
quicksort([]) -> [].
      split(Pivot, [H|T], {Acc_S, Acc_L}) ->
      if Pivot > H -> New_Acc = { [H|Acc_S] , Acc_L };
      true -> New_Acc = { Acc_S , [H|Acc_L] }
    end,
split(Pivot,T,New_Acc);
split(_,[],Acc) -> Acc.

Implement the program in an own module or integrate it where you implemented basic programming problems. Create an interface function to this module whose first parameter is the programming problem to be run, the second is the set or scalar type variable with which the program should be run. Add error handling routines to the module and to its exported functions. At this phase you can use the previously implemented error handling function which, besides the error message, also shows which function call caused it. The error handler is worth extending with a clause which does not display errors but results of the particular functions formatted according to the type of the particular return value.
