Today is Children's Day. Some children ask you to output a big letter 'N'. 'N' is constituted by two vertical linesand one diagonal. Each pixel of this letter is a character orderly. No tail blank is allowed.
For example, this is a big 'N' start with 'a' and it's size is 3.

a ebdfc g

Your task is to write different 'N' from size 3 to size 10. The pixel character used is from 'a' to 'z' continuously and periodic('a' is reused after 'z').

Input

This problem has no input.

Output

Output different 'N' from size 3 to size 10. There is no blank line among output.

Sample Output

[pre]a ebdfc gh  ni mojl pk  q.........r        j[/pre]
Hint
Not all the resultsare listed in the sample. There are just some lines. The ellipsis expresseswhat you should write.

读题很重要.... 我看了半天， 输出倒数第二行虚线是什么意思...  读了半天，参反应过来，那只是省略了 一些字符...

哎... 看来还需要做做练习....

 总之水题一道....
