  • $\begingroup$ are we to assume all intersections are standard? if not, define intersection - if I drive past an opportunity to turn right (where left is not an option), was that an intersection? If my next number is 1, should I have turned right at it? $\endgroup$ Commented Nov 25, 2015 at 17:53

    $\begingroup$ @GentlePurpleRain: It's not a dupe. The other one started with a specific sequence of turns and the knowledge that you passed a building, asking whether you would pass it again. In addition, it guaranteed that all intersections were 4-way. They're entirely different. $\endgroup$ Commented Nov 25, 2015 at 20:27

    $\begingroup$ @GentlePurpleRain I did see that question before I posted this one, but there's nothing beyond superficial similarity (i.e. that they're both graph theory based); there, you are given a sequence and asked about the result. Here, there is an intended result, and you are asked for a sequence. The answers are totally different. $\endgroup$ Commented Nov 25, 2015 at 20:55
