## Round 1 - Coding ## Problem Implement a command processor for an autonomous vehicle. The vehicle has a position `(x, y)` and a heading direction (N/E/S/W). Process a sequence of commands: `F` (forward), `B` (backward), `L` (turn left 90 deg), `R` (turn right 90 deg). Return the final position and heading. ```python def process_commands(start_x: int, start_y: int, heading: str, commands: str) -> tuple[int, int, str]: # returns (x, y, heading) ... ``` ## Example ``` process_commands(0, 0, "N", "FFRFF") # F -> (0,1,N), F -> (0,2,N), R -> (0,2,E), F -> (1,2,E), F -> (2,2,E) # -> (2, 2, "E") process_commands(0, 0, "E", "FLF") # F -> (1,0,E), L -> (1,0,N), F -> (1,1,N) # -> (1, 1, "N") ``` ## Follow-ups 1. How would you add obstacles? The vehicle should stop before hitting one and report which command failed. 2. How do you handle commands to move by variable distances, like `F3` meaning move forward 3 units? 3. Extend to support a circular grid that wraps around at the edges. 4. How would you represent and process compound maneuvers like parallel parking as a named subroutine?
