For Chinese people, 2008 is a special year. The 29th Olympic Games will be held in Beijing. In order to express our enthusiasm, we draw a big symbol '8'.

Input

Each line of input is a positive integer N (N<=40). The input file is terminated by N=0.

Output

For each input N, you should write a fixed symbol 8 using character '*' with given size N. The width of your drawing is N+1, and the height is 2*N+1. Just see the sample to understand the detail. Output one blank line after each symbol.
