Create four Red turtles and four Blue turtles using one or more lists.

Start each of the Red turtles at a different random location on the left side of the screen within the range of the square formed by $(-100,100)$ and $(0,-100)$ and each of the Blue turtles at a random location on the right side of the screen within the range of the square formed by $(0,100)$ and $(100,-100).$

Each of the red and blue turtles should move randomly.

Draw a boundary for the game as a circle with a $300$ unit radius. You will use an invisible turtle to do this. It does not count as one of the turtles on either team.

If a turtle hits the border the turtle should have its color changed to black and should jump back to the center of the screen $(0,0)$ and continue moving.

All the turtles will move the same speed.

The turtles should continue moving until $1000$ time units have elapsed.
