Step 1: Initialize coordiates and direction by setting the starting point at (0, 0) and face north.
Step 2: Process Each Instruction. For turns (left, right, around), change the facing direction.
For steps, move forward in the current direction.
Step 4: Keep Track of Changes. Update and note position and direction after each step.
Step 5: Check Final Position. Compare final coordinates with the starting point to determine if it's (0, 0).
Step 6: Output "yes" if the final coordinates are (0, 0). Otherwise, output "no" as the final answer.
