same for C translation!

I agree. The order of the traffic lights in this kata does not emulate a real traffic light. In real life, a yellow light always follows green to give the driver a short warning that the light is about to turn red.

This is not a performance kata. It can be solved without optimisations in <1 second.

so which kata made you 1dan? ;-)

Possibly because all reference solutions use an incorrect implementation of same ..

The kata is called "Simple Fun", but you're right very easy, probably should be a 6kyu not a 5.

Fixed

I would say, that this is relatively easy, but requires some coding. I mean there definitely no 'one line solution' and in order to solve this.

Even hardcoding is simple: the possible numbers are very limited...

Agreed! I really don't understand why in a game like this you'd want to be returning who just took the turn. Usually, you'd build some sort of message to the players to explain who's turn is next, not who just went.

thx :)

This isn't actionable.
