using System;

//Input
//The input data should be read from the console. You will receive an integer number X. Note that X will always be equal to Y and Z will always be (X / 2) + 1. (Refer to the examples).
//Output
//The output should be printed on the console.
//Use the “*” (asterisk) character to print the logo and “.” (dot) for the rest.
//Constraints
//•   X will always be a positive odd number between 3 and 27 inclusive.
//•   Allowed working time for your program: 0.1 seconds.
//•   Allowed memory: 16 MB.
