Tic-Tac-Toe Result

Read a tic-tac-toe board as three lines of three characters each: X, O, or - for an empty square. Print one of these:

• X wins or O wins if that player has three in a row, across, down or corner to corner
• Draw if every square is filled and nobody has won
• Not finished if there are empty squares and nobody has won

No board has two winners.

The prompts inside input() are not checked, only what you print.
