Walking Through the Robot Bounded Box: A Simulation Approach

Simulation problems are a staple in technical interviews. They test your ability to translate verbal rules into clean, state-driven code. The Robot Bounded Box (or Robot Simulation) problem is a perfect example of this, requiring us to manage directional states and collision logic efficiently. The Problem at a Glance We have a robot starting at (0, 0) facing North. We receive a list of commands: -2: Turn left 90 degrees. -1: Turn right 90 degrees. 1 to 9: Move forward $X$ units.
