Create a robocode robot called CornerBot2 that does the following:

• Visit each corner of the battlefield.
• The order in which the corners are visited does not matter.

• Another possible algorithm
  • Turn robot left until heading is an angle that is a multiple of 90º.
    • Use the modulus operator (%).
    • Get initial heading of robot.
    • Angle to turn left is ((initial heading) % 90).
      • “How many 90º angles can fit in my initial heading?”
    • Turn left to a heading that is a multiple of 90º.
  • Go ahead until I hit wall.
  • Make a 90º right turn
  • Repeat above 2 steps until I've reached all corners.
