Problem A
Point in Polygon
Input
Input contains several test cases. Each test case begins with an integer $n$ ($3 \leq n \leq 1000$). Then follow the $n$ vertices of a simple polygon, one per line, each of the form $x\ y$. The points may be given in either clockwise or counterclockwise order. Then comes an integer $m$ ($m \leq 100$), giving the number of points to test, followed by $m$ lines, each containing a point in the same format as above. Coordinates are integers with absolute value bounded by 10000. The input is terminated by a case beginning with 0.
Output
For each test case, output $m$ lines, one for each point to test. The $i$:th output for a test case should be one of “in”, “out”, “on”, depending on whether the $i$:th test point lies inside, outside, or on the given polygon.
