( 116 ) B Roads PROGRAMMING *special geometry sortings

B'The government of Treeland wants to build a new road network. There are 2N cities in Treeland. The unfinished plan of the road network already contains N road segments, each of which connects two cities with a straight line. No two road segments have a common point (including their endpoints). Your task is to determine N-1 additional road segments satisfying the following conditions: The first line of the standard input contains N ( {2 <= q N <= q 10^5} ) xe2 x80 x93 the number of existing road segments. Each of the following N lines contains four integers: x_1,y_1, x_2, y_2 , where (x_1, y_1) and (x_2, y_2) are the coordinates of the endpoints of the segment (-10^7 <= q x_i,y_i <= q 10^7) . The standard output must contain N-1 lines, each of them containing four integers, x_1, y_1, x_2, y_2 , where (x_1,y_1) and (x_2, y_2) are the coordinates of the cities that are the endpoints of a new road segment. If there are multiple solutions, your program may output any of them. '...
