Show the definition of sum by drawing a contour diagram for the code below. Show one contour diagram indicated by the * and another diagram for the **. For each * and ** draw a static and a dynamic scoped contour diagram.

begin

integer sumf;

real procedure f(x);

       value x; real x;

        f := x * x;

real proecedure sum;

    begin real S, x; s:= 0; s:=0;

        for x := x + 0.01 while x <= 1 do

            S := S + f(x);

        sum := S / 100;

     end;

begin

      real procedure f(x);

          value x; real x;

        f := x^2 + 1;

      sumf := sum;                              *

end;

begin

      real procedure f(x);

          value x; real x;

          f := cos(x) + sin(x);

      sumf := sum;                              **
