Question

In Physics, Mathematics, and related fields, a wave is a disturbance of one of more fields such that the field values oscillate repeatedly about a stable equilibrium value. Waves are usually represented using mathematical functions of the form F (x, t), where x = position and t = time.

Your task is to write a program that will visualize a given wave for exactly N seconds. You do not need to worry about evaluating the mathematical function F(x,t), as the wave will be given to you using its sample representation.

The sample representation of a wave is a series of points that represents the result of the F(x,t) function at each given t. In this problem, you will be given N samples (one for each second) represented by N integers Yi, which represents the vertical coordinate of the wave at time i.

Format Input

The first line contains a single integer N, the number of seconds you need to visualize the wave for. The next line contains N integers Y1, Y2, · · · , Yn as described in the problem statement.

Format Output

Visualize the wave given in the input. The wave should be visualized using a rectangle N characters long and 9 characters tall. Coordinates where the wave is currently in should be represented using the # (hash) character whilst empty coordinates should be represented using the . (dot) character. For clarity, please refer to the sample output section.
