Twenty Circles
Problem Statement:
Modify the blocks so that the robot traces over the twenty circles.
```/* Code generated by RoboBlockly v2.0 */
double degrees;
double trackwidth = 3.69;

// Repositions the robot to the next starting point of the next circle
void nextCircle() {
}
int count;

// Create a circle of given radius
robot.traceOn();
count = 0;
while(count < 360) {
count = count + 1;
}
robot.traceOff();
}
int count2;

degrees = 0;
count2 = 0;
while(count2 < 20) {
robot.traceColor("red", 3);
degrees = degrees + -18;
Circle(3);
nextCircle();
count2 = count2 + 1;
}
