0 curr3nt Posted April 20, 2011 Report Share Posted April 20, 2011 Four odd numbers separated by an even number contradicts the code ending with two even numbers. OEOEOEO leaves 1 E and 1 O with no way to get two E on the end. Are the instructions incorrect or is there a trick involved or wrapping counts?

0 curr3nt Posted April 20, 2011 Report Share Posted April 20, 2011 (edited) I think the numbers 1-9 are supposed to each be used. Otherwise there are too many combinations that would work. Edited April 20, 2011 by curr3nt Quote Link to comment Share on other sites More sharing options...
0 Guest Posted April 20, 2011 Report Share Posted April 20, 2011 431259786 4 odd numbers are separated by an even number means OO E OO ,simple logic if v separate 2 people means they will be separated 1+1 . Here 31 2 59 are separated by 2. Quote Link to comment Share on other sites More sharing options...

With this restriction, there are still 222 of them! Quote Link to comment Share on other sites More sharing options...
