CitiBank quant interview question:



4 coins are placed at the corners of a rotating table and the player is blindfolded. At every turn, the player can flip as many coins as he wants, and ask the game master if the coins are all showing heads. If they are all heads, the player wins, otherwise the game master can arbitrarily rotate the table before the next turn. Is there a winning strategy for the player?
