You will be given two-dimensional coordinates of points. Your task is to identify points from them that are lying in a straight line (This line should contain exactly points). It is guaranteed that all points are unique and there is exactly one such line exists in which exactly points lie.
The first line of the input contains two integers and .
The next lines contain the description of points. The th line contains two integers and that denote the coordinates of the th point.
Print the coordinates of the points one line each according to the input order.
