Problem 194. Clockwise or Counterclockwise
added more samples to the test
Hello, Alfonso Nieto-Castanon. This is a very nice problem. It was interesting to see the variety of approaches used to solve it. It was also interesting to notice a few submissions failed your added test cases from circa Dec 2017. Do you allow for self-intersecting polygons, as per https://en.wikipedia.org/wiki/Polygon ?
I suspect a common solution tactic will fail badly when faced with self-intersecting polygons. —DIV
...On second thought, maybe there's no consistent definition of CW/CCW for self-intersecting polygons, such as figure-eight or bow-tie ("cross-quadrilateral") shapes.
