#931

Se dau puncte distincte în plan. Asociem fiecărui punct semidreapta care pornește din originea sistemului de coordonate și trece prin acel punct. Să se afișeze punctele în ordine crescătoare a unghiului pe care semidreapta asociată îl face cu semidreapta spre plus infinit a axei OX. Dacă două unghiuri sunt egale se va afișa punctul cel mai apropiat de origine.
