     i := i + 1;
   }
a := sum;

Which of the following is a correct translation from high to low level?

   sum := 0;
place1
   sum := sum + i;
   i := i + 1;
   if (i<n) then goto place1;
   a := sum;

   i := 0;
   sum := 0;
place1
   if (i<n)=False then goto place2;
   sum := sum + i;
   i := i + 1;
   goto place1;
place2
   a := sum;
