Thanks for the answer of #7, now I only have to think trough your explanation. This was the most difficult question of this year for me (besides 11 and 13, which took me some time to solve successfully)
Does somebody understands why "Cube Travel" is not included in the final score? In one intermediate score I was quite happy about the 135 points I got for my answer and as far as I can see the solution is clear and well defined or what am I missing?
Also I'm surprised that my answer of #20 is told to be wrong but lets see what the judges say...
//Edit: OK, I found my mistake, I solved it for sums of a^3 instead of sums of 3^a....They even give explicit numbers in the puzzle, I should have read it more carfully.
I had a very good feeling this year but the competitors seem to become stronger (last year I had 3 questions wrong and ended up place 30, this time 2 questions wrong and place 39) Unfortunately the score board of last year seems to be gone and all the other score boards are without points.
