题目描述

What's the feeling of designing an icon for a school as a programmer? Now you have a chance doing it!

The icon of Nanjing Foreign Language School (NFLS for short) is not complicated, it can be represented as an ASCII art.

Since the icon might be used in different places, you need to print the icon in different size.

Given size $n$ , print the icon of size $n$ .

Detailed format is shown below, you can also look at the sample output to confirm it.

Like which is shown in the picture, '*' is used on the boundary, and '@' is used for the letters.

$(n+1)$ '.'s are used to seperate letters and the boundary horizontally, and $n$ '.'s are used vertically.

Each letter is $(2n+3)$ characters wide and $(2n+3)$ characters in height.

The icon's size is $(4n+5) × (13n+19)$ .

输入描述:

The first line contains a positive integer , representing the size of the icon.

输出描述:
