| Feb 17, 2017 at 5:38 | comment | added | elias | Although this does not match the scenario I described above (reducing the 3-guard question to the 2-guard one), I have to agree this is a nice find. I hoped I excluded solutions with one question with the criteria about hypothetical questions, but your answer clearly shows that I did not. Thanks! | |
