# The code below will read all the game information for you.
# On each game turn, information will be available on the standard input, you will be sent:
# -> the total number of visible enemies
# -> for each enemy, its name and distance from you
# The system will wait for you to write an enemy name on the standard output.
# Once you have designated a target:
# -> the cannon will shoot
# -> the enemies will move
# -> new info will be available for you to read on the standard input.
