We have a special convex that all points have the same distance to origin point. As you know we can get N segments after linking the origin point and the points on the convex. We can also get N angles between each pair of the neighbor segments. Now g…

Given a list of points that form a polygon when joined sequentially, find if this polygon is convex (Convex polygon definition). Note: There are at least 3 and at most 10,000 points. Coordinates are in the range -10,000 to 10,000. You may assume the…
