查找正多边形的内部和外部角度的程序

给定规则多边形的边数n。任务是找出多边形的内角和外角。
例子：

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

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

内角：多边形内两个相邻边之间的角度称为内角。
查找内角的公式：
内角= $\frac{(n-2)\times 180}{n}$
外角：多边形任意一侧与其相邻边的延长线所形成的角度称为外角。
外角= $\frac{360}{n}$
