# Hints

## General
|
|
|
|
- This challenge is all about calculating if a point falls _on, in, or outside_ a given circle.
|
|
- There are two different ways of calculating if a point falls on, in, or outside a circle.
|
|
- This _Stack Overflow_ Post: [Equation for Testing if a Point is Inside a Circle][point-circle-equation] outlines one method.
|
|
- This _DoubleRoot_ post [Position of a point relative to a circle][point-to-circle] outlines a different one.
|
|
- This _Math is Fun_ post covers a more general [Distance Between 2 Points][distance-between-two-points] calculation.
|
|
- Because the dart board is a set of _concentric_ circles, the order in which you calculate points could change the answer significantly.
|
|
You should pay attention to which direction your calculations "move" in.
|
|
- Remember that this exercise has many potential solutions and many paths you can take along the way.
|
|
No path is manifestly "better" than another, although a particular path may be more interesting or better suited to what you want to learn or explore right now.
|
|
- Some paths may trade speed for clarity.
|
|
Others might take up more memory but be more scalable or maintainable.
|
|
- We encourage you to try out more than one programming strategy to see what happens.
