SOLUTION To Sunday Puzzle #36: Surveying The Mad King’s Kingdom
Last workweek , I challenged you to deduce how you and a fellow inmate win your freedom on your fifth day of captivity by a sore king . The key to work out the puzzle , I suggest in the deed of the post , was to think like two the great unwashed : yourself , and your fellow captive .
Several of you get in at the correct conclusion , butcommenter trimeta provide the most thoroughgoing summing up of both prisoners ’ logic , and why the captives won their freedom on their fifth daylight of imprisonment , and no sooner :
Day 1 : if one prisoner fancy 11 , 12 , or 13 Village , then they can be certain there are 13 villages , and will say so at 5 PM on this 24-hour interval .
Day 2 : if one prisoner sees 0 , 1 , or 2 villages , they can be sealed that * if * there were 13 settlement , then the other prisoner would have seen 11 , 12 , or 13 villages , and would have call out the answer on Day 1 . Since they did n’t , they can be sealed there are 10 villages , and will say so at 5 PM on this Clarence Shepard Day Jr. .
Day 3 : if one captive sees 8 , 9 , or 10 Village , they can be certain that * if * there were 10 village , the other prisoner would have pick up 0 , 1 , or 2 villages , and would have call out the solvent on Day 2 . Since they did n’t , they can be certain there are 13 hamlet , and will say so at 5 PM on this day .
Day 4 : if one captive sees 3 , 4 , or 5 small town , they can be certain that * if * there were 13 village , the other prisoner would have seen 8 , 9 , or 10 villages , and would have ring out the solution on Day 3 . Since they did n’t , they can be sure there are 10 villages , and will say so at 5 phase modulation on this daytime .
Day 5 : if one captive witness 6 or 7 hamlet , they can be certain that * if * there were 10 villages , the other prisoner would have realise 3 or 4 villages , and would have called out the answer on Day 4 . Since they did n’t , the other captive must also be seeing 6 or 7 villages , and both prisoners are sealed there are 13 hamlet and will say so at 5 premier on this day .
