Trivia Quiz : Floral fortune-telling (Level 2）
There is a flower with 13 petals as shown in the figure below.
2 people decide an order to take petal.
One petal or two petals adjacent for once are taken in turn.
There is a legend that fortune visits for the person who takes the last petal.
When you do this floral fortune-telling with somebody, do you choose the first taker or the second taker in your turn?
This game is certain victory of the second taker.
If the first taker takes two pieces, the second taker takes one piece.
Thereafter the second taker takes same number of pieces in the other side as number the first taker takes.
Then it is always the second taker who takes last petal.
