Question 15
On Beaver Island, carrots grow in 5 rows with 7 carrots in each row, as shown below.
The beavers use a robot to harvest the carrots with these instructions:
- P – Find a carrot in the same row and harvest it.
- F – Go straight along the same row.
- D – Go down to the next row.
- U – Go up to the next row.
- R – Turn right by 90 degrees.
- L – Turn left by 90 degrees.
Numbers can represent repeated instructions. For example, 3P means harvest 3 carrots in the same row. Which of the following instructions can make the robot harvest all the carrots?
