How can Karel turn right using available commands?

In the context of Karel the robot's movement commands, Karel can turn right by executing a series of left turns, since Karel primarily has a turnLeft() function. Turning left once rotates Karel 90 degrees counterclockwise. Therefore, to achieve a right turn, Karel can turn left three times, resulting in an effective 270-degree turn to the left, which is equivalent to a right turn.

This method effectively allows Karel to change direction without needing a dedicated right turn command. The other methods, such as calling turnLeft() once or twice, do not result in a right turn, and using move() in conjunction with turnLeft() is irrelevant since it doesn’t coordinate the appropriate number of turns needed to achieve a right-facing position.
