Direction Sense Strategy
Step 1: Track position on coordinate grid (East = +x, North = +y)
Start at (0,0) facing North
Step 1: Move +8 in x-direction
Step 2: Move +6 in y-direction → position updates
Step 3: Move -8 in x-direction
Step 4: Move -4 in y-direction
Final Position: (0, 2)
Final Facing Direction: South
