Multiple Turns
Multiple Turns problems involve a person making a sequence of two or more left/right turns. You must determine the final facing direction after applying all turns in order. These problems test your ability to apply sequential rotations and track cumulative directional changes.

Multiple Turns problems involve a person making a sequence of two or more left/right turns. You must determine the final facing direction after applying all turns in order. These problems test your ability to apply sequential rotations and track cumulative directional changes.
Prerequisites
How to Solve Multiple Turns Problems
Step 1: Identify the starting direction
Step 2: List the turn sequence in order (e.g., left, right, right)
Step 3: Apply turns one by one using the basic turn rules
Step 4: After each turn, update the current facing direction
Step 5: Alternative: Count net turns (right = +1, left = -1) and apply net rotation modulo 4
Step 6: The final direction after all turns is the answer
Step 7: Verify by checking that 4 turns (or multiples of 4) return to original direction
Example Problem
Example: A person is facing East. He turns left, then right, then right. Which direction is he now facing? Solution: Step 1: Start = East Step 2: Turn1 = left: East → North Step 3: Turn2 = right: North → East Step 4: Turn3 = right: East → South Step 5: Final direction = South Answer: South Alternative: Net = -1 (left) +1 (right) +1 (right) = +1 → from East, +1 = South
Pro Tips & Tricks
- Net turns = (number of right turns) - (number of left turns)
- Net rotation = (Net turns × 90°) mod 360
- If net turns mod 4 = 0 → same direction
- If net turns mod 4 = 1 → turn right once
- If net turns mod 4 = 2 → opposite direction (180°)
- If net turns mod 4 = 3 → turn left once (or right 3 times)
