Given an essence N representing N sided constant polygon, the task is to discover the edge made through the political parties on the centre of the polygon the is the central angle.The central angle is the angle developed by the two vertices forming an edge and the centre.

Input: N = 5Output: 72Explanation:The polygon is a pentagon through an angle 72 degree.
Approach: The idea is to observe that since there is a regular polygon all the central angles formed will be equal.All central angles would add up come 360 degrees (a full circle), so the measure of the central angle is 360 divided by the variety of sides.Hence, central angle = 360 / N degrees, whereby N is the number of sides.Below is the implementation the the over approach:
Find three vertices in an N-sided consistent polygon such the the angle subtended in ~ a peak by two various other vertices is closest come A
