Write a function that returns the earned points in a single toss of a Darts game.
In our particular instance of the game, the target rewards with 4 different amounts of points, depending on where the dart lands:
The outer circle has a radius of 10 units (This is equivalent to the total radius for the entire target), the middle circle a radius of 5 units, and the inner circle a radius of 1. Of course, they are all centered to the same point (That is, the circles are concentric) defined by the coordinates (0, 0).
Write a function that given a point in the target (defined by its
real cartesian coordinates
y), returns the correct amount earned by a dart landing in that point.
