Personally, however, I prefer the previous, slightly longer code. It offers more protection against degenerate systems, especially since, as I mentioned before, the 15C does not alert you when it encounters one, but alters it slightly so as to be able to come up with *a* solution - even if it is only one of infinitely many.
