• it is said that among 2 players only one is selected as winner.
  At the 8th round one player is declared as winner. Which means that there were 2 players playing at the 8th round.
  In order to get 2 players ath the 8th round there must be 4 players at the 7th round so that 2 are selected to the 8th round.
  Hence, there are
  8 players at 6th round
  16 players at 5th round
  32 players at 4th round
  64 players at 3rd round
  128 players at 2nd round
  256 players at 1st round
  
  Hence the answer is 256
