Input : N = 6
Output : 6 2
The image below is of a triangle forming inside a Hexagon by joining vertices as shown above.
The triangle formed has two sides (AB and BC) common with that of a polygon. Similarly BC and
CD can make one triangle. With this, we can say that there will be a total of 6 triangles possible
having two sides common with that of a polygon. The second image of a hexagon,
a triangle is formed with no side common with that of a polygon.
There will be just 2 triangles possible, BFD and ACE.
Triangle with two side common and no side common of the Hexagon
Number of triangles formed are 6 and 2 with two side common and with no side common respectively.
Input : N = 7
Output : 7 7
