问题描述

　　聪明的昆哥发明了一个游戏，在六边形的棋盘上放一些棋子（如下图），参与者轮流从棋盘上取平行于某条边的相邻的若干棋子，当棋盘上没有棋子可以取的时候就说明当前要取棋子的人输了。

另外：本来昆哥是希望实验室的同学都来参加比赛（多人博弈），但是他觉得如果棋盘太大，或者参加的人数太多他就不能很好的控制输赢了，他不喜欢不能控制的东西。他喜欢Everything is under control。所以他就设计了这个双人游戏，并且棋盘为固定的六边形，最多可以安放 19 个棋子。

玲玲姐和昆哥都很聪明，他们决定要进行一场比赛。因为昆哥觉得自己的智商碾压玲玲姐，所以让玲玲姐决定谁先选棋子。

★目标：

　　给出棋盘，请告诉玲玲姐是先选还是后选棋子-Problem Descr iption Kunge invented a clever game, put some pieces (see below) on the hexagonal board, players take turns　the board to take certain parallel edges adjacent to several pieces, no pieces on the board when When can I take to explain the current to take pieces of people lost. Also: Originally Kunge hope lab students have to participate in the competition (multiplayer games), but he felt that if the board is too big, or too much the number of participants, he can not win or lose good control, and he does not like can not control s thing. He liked Everything is under control. So he designed this double game, and the board is fixed hexagon, can be placed up to 19 pieces. Lingling sister and Kunge are smart, they decided to carry out a game. Because Kunge think his IQ rolling Lingling sister, so let Lingling sister decide who should choose a pawn. ★ goal: to give the board, please tell Lingling sister is a piece before the election or after the election
