Problem：
There are n points on an ellipse, connecting them, and asking how many parts can be divided into.
solution：
There are n points, and a circle is divided into n parts.

Detailed deduction process:

The amount of data in thehttps://en.wikipedia.org/wiki/Dividing_a_circle_into_areas
http://www.arbelos.co.uk/Papers/Chords-regions.pdf

and the amount of data in the title requires us to use high -precision operations.

To do more questions, master a lot of questions and then look back.
