There is a game where each player picks a number from 1 to 9, writes it on a paper and gives to a guide. A player wins if his number is the lowest unique. We may have 10-20 players in our game.
Your program should accept as its first argument a path to a filename.
You're a guide and you're given a set of numbers from players for the round of game. E.g. 2 rounds of the game look this way:
3 3 9 1 6 5 8 1 5 3 9 2 9 9 1 8 8 8 2 1 1
Print a winner's position or 0 in case there is no winner. In the first line of input sample the lowest unique number is 6. So player 5 wins.
