NoCOUG Third SQL Challenge

Boy that was fun. Not revealing my answer to wider audience just jet as the competition just started. Try it yourself. Breadth first seems to do less than depth first. Maybe that is why it is the default in recursive common table expression.
Update 28.5.2012 additional rules published. Made the question a bit harder than it seemed at first try. Well that is just software testing, when solving complex tasks. Test data and desired answers are required.
