Subtraction: Catch the football
Problem Statement:
A subtraction problem is shown on the grid and a football will be thrown the location of the result. Drive your robot to the football location to catch the football
```/* Code generated by RoboBlockly v2.0 */
/* Problem Statement:
There is an addition problem on the left corner of the
grid. A football will be thrown to the location equals to
the result of that addition problem. Your job is to drive
the robot to catch the football. */
