Hello Ana,
It may be possible that your code would work. However, please be aware
that it was *very* complicated to get the current code to produce the
right results. It is very easy to get an answer that is wrong by 1 hour
or something like that.
Thus anything that one would submit would need to be *really* well tested.
Best regards,
Kern
