Q, you should be far smarter than me. How come you solved it just 0.0001 sec faster? I expect you can solve it without drawing a chart in 1 minute.  >:(

I solved it, with the help of a computer, which the solution comes out instantaneously, in 18ms.


--- Code: ---| ?- solution(Houses).

Houses = [(nigel,purple,tiger,green_tea,daily_express),(vlad,blue,stallion,vodka,guardian),(jez,red,eagle,milk,morning_star),(donald,green,fish,coffee,daily_mail),(liz,white,corgis,beer,times)] ? a

(18 ms) no

--- End code ---

The above is a list containing the solution, first tuple is the first house's characteristics, etc.  It's a Prolog program.
