Problem Description
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 e
bdf
c 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
a e
bdf
c g
h n
i mo
jl p
k q
.........
r j
Hint
Not all the resultsare listed in the sample. There are just some lines. The ellipsis expresseswhat you should write.
