problem_description: Statement
  
  There is a set A = \\{ a_1, a_2, \ldots, a_N \\} consisting of N positive
  integers. Taro and Jiro will play the following game against each other.
  
  Initially, we have a pile consisting of K stones. The two players perform the
  following operation alternately, starting from Taro:
  
    * Choose an element x in A, and remove exactly x stones from the pile.
  
  A player loses when he becomes unable to play. Assuming that both players play
  optimally, determine the winner.
