<strong>Input</strong>
[&quot;Robot&quot;, &quot;move&quot;, &quot;move&quot;, &quot;getPos&quot;, &quot;getDir&quot;, &quot;move&quot;, &quot;move&quot;, &quot;move&quot;, &quot;getPos&quot;, &quot;getDir&quot;]

[[6, 3], [2], [2], [], [], [2], [1], [4], [], []]
<strong>Output</strong>
[null, null, null, [4, 0], &quot;East&quot;, null, null, null, [1, 2], &quot;West&quot;]
<strong>Explanation</strong>
Robot robot = new Robot(6, 3); // Initialize the grid and the robot at (0, 0) facing East.
robot.move(2); // It moves two steps East to (2, 0), and faces East.
robot.move(2); // It moves two steps East to (4, 0), and faces East.
robot.step(2); // It moves two steps East to (2, 0), and faces East.
robot.step(2); // It moves two steps East to (4, 0), and faces East.
robot.getPos(); // return [4, 0]
robot.getDir(); // return &quot;East&quot;
robot.move(2); // It moves one step East to (5, 0), and faces East.
robot.step(2); // It moves one step East to (5, 0), and faces East.
// Moving the next step East would be out of bounds, so it turns and faces North.
// Then, it moves one step North to (5, 1), and faces North.
robot.move(1); // It moves one step North to (5, 2), and faces <strong>North</strong> (not West).
robot.move(4); // Moving the next step North would be out of bounds, so it turns and faces West.
robot.step(1); // It moves one step North to (5, 2), and faces <strong>North</strong> (not West).
robot.step(4); // Moving the next step North would be out of bounds, so it turns and faces West.
// Then, it moves four steps West to (1, 2), and faces West.
robot.getPos(); // return [1, 2]
robot.getDir(); // return &quot;West&quot;
