I came back to think about this and I noticed a mistake: On Wed, Jun 19, 2019 at 10:12 AM Raul Miller <[email protected]> wrote: > I don't know what the tenth value would be. (If I remove the "1" coin, > I get 18 values that can't be paid with three coins.)
That should have been: ... that can't be paid with less than three coins. I suppose it's possible that the tenth value might be zero? But then the problem statement would have been "that can't be paid with one or two coins" and we would have an implicit constraint against a "0" coin. I do have that implicit constraint in my implementation in this thread, but... I can't quite make sense of 0 being the tenth value we couldn't pay with less than three coins... Not sure if this is of any help, though. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
