problem_description: Statement
  
  Alice and Brown loves games. Today, they will play the following game.
  
  In this game, there are two piles initially consisting of X and Y stones,
  respectively. Alice and Bob alternately perform the following operation,
  starting from Alice:
  
    * Take 2i stones from one of the piles. Then, throw away i of them, and put the remaining i in the other pile. Here, the integer i (1≤i) can be freely chosen as long as there is a sufficient number of stones in the pile.
  
  The player who becomes unable to perform the operation, loses the game.
  
  Given X and Y, determine the winner of the game, assuming that both players
  play optimally.
