B'You are given a tree with n vertexes and n points on a plane, no three points lie on one straight line. Your task is to paint the given tree on a plane, using the given points as vertexes. That is, you should correspond each vertex of the tree to exactly one point and each point should correspond to a vertex. If two vertexes of the tree are connected by an edge, then the corresponding points should have a segment painted between them. The segments that correspond to non-adjacent edges, should not have common points. The segments that correspond to adjacent edges should have exactly one common point. The first line contains an integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891500) -- the number of vertexes on a tree (as well as the number of chosen points on the plane). Each of the next n xe2 x80 x89- xe2 x80 x891 lines contains two space-separated integers ui and vi (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89ui, xe2 x80 x89vi xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n, ui xe2 x80 x89 xe2 x89 xa0 xe2 x80 x89vi) -- the numbers of tree vertexes connected by the i-th edge. Each of the next n lines contain two space-separated integers xi and yi ( xe2 x80 x89- xe2 x80 x89109 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89xi, xe2 x80 x89yi xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109) -- the coordinates of the i-th point on the plane. No three points lie on one straight line. It is guaranteed that under given constraints problem has a solution. Print n distinct space-separated integers from 1 to n: the i-th number must equal the number of the vertex to place at the i-th point (the points are numbered in the order, in which they are listed in the input). If there are several solutions, print any of them. The possible solutions for the sample are given below.'...
