Provide tags and a correct Python 3 solution for this coding contest problem. There is a forest that we model as a plane and live n rare animals. Animal number i has its lair in the point (x_{i}, y_{i}). In order to protect them, a decision to build a nature reserve has been made. The reserve must have a form of a ci...
