Create Trapezoid

Write a program that prints on the console the border of a trapezoid by given number N.
The width of the top side of the trapezoid must be exactly N.
The width of the bottom side of the trapezoid must be exactly 2 * N.
The height of the trapezoid must be exactly N + 1.
Also the top right and the bottom right angle of the trapezoid must be equal to 90 degrees.
See the examples bellow.
Input
The input data is being read from the console.
On the only line in the console you are given an integer number N, showing the width of the smallest trapezoid side.
The input data will always be valid and in the format described. There is no need to check it explicitly.
Output
The output data must be printed on the console.
You must write the border of the described trapezoid on the console.
Use the symbol “*” (asterisk) to mark the border of the trapezoid.
Use the symbol “.” (dot) to illustrate the empty spaces outside and inside the trapezoid.
Constraints
•	The number N is a positive integer between 3 and 39, inclusive.
•	Allowed working time for your program: 0.25 seconds.
•	Allowed memory: 16 MB.
