The answer is the symmetry axis In test 3 the angle between the lines is very small Edited by author 26.06.2015 02:34 thx! <code> #include <stdio.h> int main(){ printf("1 1 0\n0 0 0\n180\n"); } </code> gives WA3 ^) My solution only outputs alpha=180. Is there any case that it's possible and alpha can't be 180? Alpha can always be 180. Oh Yes! Understanding this fact makes the problem being quite easy. The only problem is to output points with |coordinates| <= 2000. But I didn't have to care about it because of weak tests. del Edited by author 06.05.2015 12:45 My first solution outputs points P and Q with coordinates more than 2000 on test 0 1000 0 1000 999 0 0 0 0 1 0 0 but passes jury tests.
