What happens to Karel when facing south in the Right Side Up function?

When Karel is facing south in the Right Side Up function, the action involves Karel turning right twice. This is because turning right from a southward direction will first point Karel to the west, and then after another right turn, Karel will be facing north. Each right turn adjusts Karel's orientation by 90 degrees, fulfilling the requirement of the Right Side Up function to reposition Karel appropriately.

Turning right twice effectively reorients Karel from south to north, which is essential for completing tasks that follow in Karel's programming environment. Understanding this directional logic is crucial for manipulating Karel's movements effectively within a grid-based scenario.
