There is nothing there that depends on the order of j values.  If
coefficients(7) = 3, then result(7+16=23) := '3', quite independent of
any previous or later value of j.
  Perhaps you want result(16-j) instead of result(16+j), so
result(-7+16=9) would get the '3'.
  Getting stuck on this kind of problem is a good indication it's time
to take a break from your program.
