In the game Flying Monsters, we will be transported to the world populated with funny monsters, who spend their free time in various games. Today they decided to play a game that checks the accuracy and the eye of the player. We will join them. On the screen on the field will be installed slingshot in which the monster will sit. Somewhere at a certain distance there will be a circle. You need to calculate the speed and trajectory of the throw so that our monster flying through the air hit the ring. In total, you will have three attempts at these actions. And if you do not get there, you'll lose the round. So try to aim carefully and only then make a shot.
