@JoeZ. - I didn't explicitly account for that (as evidenced by the issues with my 2nd hint), however, 8333 => 112 would definitely be the answer due to the nature of the algorithm (see follow up comments on your answer).

| Apr 5, 2015 at 22:38 | comment | added | Alconja | ...although embarrassingly I've just realised that hint falls down with certain values... (which you would see even with the systems proposed in this answer/comments, e.g. 1111111111) | |
| Apr 5, 2015 at 21:49 | comment | added | Alconja | @EngineerToast - did your solution account for 19? | |
| Apr 5, 2015 at 21:48 | comment | added | Alconja | @Kay - 95 => 111, 91 => 111. Like I said to Jonathan, you're very close, but the solution is simpler... Take another look at my second hint. | |
| Apr 5, 2015 at 10:38 | comment | added | Kai | 95 => 111, 91 => 12 correct? | |
| Apr 5, 2015 at 10:20 | comment | added | Kai | If we expand "and the result is how many numerals in a row begin with a '5' or '1'" with "and next arabic number is smaller", we can cover 19. 19 => 21 (XIX \ 10,1,10). So first two roman chars are sequence, third starts new sequence. | |
| Apr 3, 2015 at 21:32 | comment | added | Alconja | So close. But as you note it falls down on 19... the solution is actually slightly simpler than what you're doing. | |
| Apr 3, 2015 at 15:20 | comment | added | Engineer Toast | I was tempted to post my own with a better explanation but Jonathon figured it out first and deserves the points. | |

Add clarification and breakdown for each input / output combination

| Apr 3, 2015 at 14:49 | comment | added | leoll2 | "how many numerals in a row begin with a '5' or '1' " isn't very clear, I don't understand its meaning. I don't understand how you got 122 from XLVII, please add more details :-) | |
