Create a C# program

Given an n $-$sided regular polygon n $,$ return the total sum of internal angles $($in degrees$).$

n will always be greater than $2.$

The formula $(n-2)180$ gives the sum of all the measures of the angles of an $n-$

sided polygon.

Define Main Structure: Create a class with a method SumPolygon

The SumPolygon method should accept one int as an argument and then return a

value based on the formula above. Examples:

SumPolygon $(3)180$

SumPolygon $(4)360$

SumPolygon$(6)720$

Use the console to test input as a command line argument or hard code ints
