How do you move Karel to the next line in a vertical orientation?

To understand how to move Karel to the next line in a vertical orientation, it's important to visualize Karel's position and how its movements work. When Karel is facing up or down, moving to the next line vertically typically involves turning Karel to face a direction that allows for movement in the vertical plane.

Using a combination of move() and turnLeft() is effective because, after moving vertically (up or down), Karel may need to change direction to continue its journey or to move to the next line. For example, if Karel is facing up and wants to move to the left or right, it would use turnLeft() to change its direction and then move() to advance to the next space. This combination allows Karel to navigate correctly and efficiently.

The method of using move() alone would not suffice to transition between lines as Karel could only move forward in the same direction it is facing. Similarly, relying solely on turnAround() would only rotate Karel but not facilitate movement. Therefore, the combination of movements alongside turning is crucial for achieving efficient navigation in both horizontal and vertical orientations.
