Problem 46571. Characterize the final state of the digit inventory sequence
Rats. My solution got all the problems right except the last. How is that possible?
William, our results differ for a starting value of 570. I'm not sure why yet.
William, I think I see the reason for the difference now. Let me know if you want a hint.
Aha! I see the problem with 570. Very clever of you to include a case like that!
Thanks but I'd say I was more lucky than clever. A run of periods drew me to that range. You're right that the case of 570 is a good one.
