One way to determine whether a point p0

One way to determine whether a point p0 is in the interior of a simple, but not necessarily convex, polygon P is to look at any ray from p0 and check that the ray intersects the boundary of P an odd number of times but that p0 itself is not on the boundary of P. Show how to compute in Θ(n) time whether a point p0 is in the interior of an n-vertex polygon P. (Hint: Use Exercise 33.1-6. Make sure your algorithm is correct when the ray intersects the polygon boundary at a vertex and when the ray overlaps a side of the polygon.)
