( 4312 ) D Pair Of Lines PROGRAMMING geometry 1900

B'You are given n points on Cartesian plane. Every point is a lattice point (i. xe2 x80 x89e. both of its coordinates are integers), and all points are distinct. You may draw two straight lines (not necessarily distinct). Is it possible to do this in such a way that every point lies on at least one of these lines? The first line contains one integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105) -- the number of points you are given. Then n lines follow, each line containing two integers xi and yi (|xi|, xe2 x80 x89|yi| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109) -- coordinates of i-th point. All n points are distinct. If it is possible to draw two straight lines in such a way that each of given points belongs to at least one of these lines, print YES. Otherwise, print NO. In the first example it is possible to draw two lines, the one containing the points 1, 3 and 5, and another one containing two remaining points. '...
