Program to find the Interior and Exterior Angle of a Regular Polygon

Given the number of sides n of a regular polygon. The task is to find out the Interior angle and Exterior angle of the polygon.
Examples: 
 

Input : n = 6
Output : Interior angle: 120
 Exterior angle: 60

Input : n = 10
Output: Interior angle: 144
 Exterior angle: 36

Interior angle: The angle between two adjacent sides inside the polygon is known as the Interior angle. 
Formula to find the Interior angle:
Interior Angle = 
Exterior angle: The angle formed by any side of a polygon and the extension of its adjacent side is known as Exterior angle.
Exterior angle =
