/**
 * CodinGame planet is being attacked by slimy insectoid aliens.
 * <---
 * Your program must destroy the enemy ships by shooting the closest enemy on each turn.
 *Rules
 *
 *On each start of turn (within the game loop), you obtain information on the two closest enemies:
 *enemy1 and dist1: the name and the distance to enemy 1.
 *enemy2 and dist2: the name and the distance to enemy 2.
 *Before your turn is over (end of the loop), output the value of either enemy1 or enemy2 to shoot the closest enemy
