It seems to me that the logic of the test suite is reversed. You're asking if the numbers are coprime and yet want 0 (false) when they are.

@Guillaume: Your are right.
I re-wrote the text. The english got worse, but the clarity increased, I hope:))

I submitted this just to see if one can get away with a blatant cheat!

Until the test suite is changed, yes. Yes you can.

George-Felix Leu on 6 Jan 2016

Well, test suite changed :)
Does the "tf = n1==27" still work? :)

Are Mjaavatten on 6 Jan 2016

My cheat does not pass new test suite, but tf = n2==123 does.

George-Felix Leu on 6 Jan 2016

@Are Mjaavatten: Your are terrible:). I will change (improve:)) again the test-suite.
