Square in the Coordinate Plane
Problem Statement:
The pre-placed block will draw one side of the square with side length 4. Add blocks to draw the remaining three sides of the square. Remember that squares have equal sides and four 90 degree angles.
```/* Code generated by RoboBlockly v2.0 */
double trackwidth = 3.69;
int count;

count = 0;
while(count < 4) {
count = count + 1;
}
```
```/* Code generated by RoboBlockly v2.0 */
double trackwidth = 3.69;
