BMAD Posted July 6, 2013 Report Share Posted July 6, 2013 Create the shortest possible sequence such that no number is next to its first-hand or second-hand neighbors (e.g., the number 3 cannot be next to numbers 1, 2, 4, or 5, which are first- and second- neighbors).

0 BMAD Posted July 6, 2013 Author Report Share Posted July 6, 2013 3,6,2,5,1,4 is a 5 sequence possible? Quote Link to comment Share on other sites More sharing options...
0 Nins_Leprechaun Posted July 7, 2013 Report Share Posted July 7, 2013 3,6,2,5,1,4 is a 5 sequence possible? No as there would be a number that could not be beside any other. For example in a sequence of numbers 1-5 the number 3 could not be beside any other number making a run of 5 (or less) impossible. Quote Link to comment Share on other sites More sharing options...

0 BMAD Posted July 7, 2013 Author Report Share Posted July 7, 2013 i should have been more clear in the op, the sequence must start at 1 and go to some n greater than 1 (consecutively). Quote Link to comment Share on other sites More sharing options...
