If a computational geometer incrementally constructs a convex hull from a point set using Graham's scan, which outcome occurs when the current point creates a non-left turn?

💡 Explanation

When a non-left turn is detected, the Graham scan convex hull algorithm backtracks because it indicates the previous point is not part of the convex hull; therefore, the previous point is removed from the hull, rather than advancing or terminating the calculation.
