# # The Tron Problem
#
# '''
# Greetings future XXXXXXXXXX employee! You have been "randomly" selected to participate in the 11th annual Tron games!
# Don't worry, you won't be actually playing the games.
# You'll be judging the battles after the fact! Let me take a quick second to brief you on the Tron Standard Rules (TSRs).
#
# 1) The game is played on a standard 10x10 board
# 2) Player 1 starts on position 0x0. Player 2 starts on position 9x9
# 3) At each turn, a player may move up, down, left, or right on the board. These steps are held in an array and take the form 'u','d','l', and 'r' respectively.
# 4) If a player crosses a previous path of another player, including themselves, they are eliminated
# 5) If a player lands on the same space as another player on the same turn, both players are eliminated and the match is declared a draw
# 6) If a player moves off the board, into the vast cyber nothingness, they are eliminated
# 7) If there is only one player left at the end of a turn, that player wins no matter if they have more moves or not
# 8) If the match has ended and there is more than one player still active, the match is declared a draw
# '''
