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

[pre] a e bdf c g h n i mo jl p k q ......... r j [/pre]

程序代码：

#include #include #include using namespace std; char  mapp[11][11]; int main() {     char a='a';     for(int n=3;n<=10;n++)     {         memset(mapp,0,sizeof(mapp));         for(int i=0;i'z')  a-=26;             mapp[i][0]=a++;//重点理解，把复杂问题简单化         }     for(int i=n-2;i>=1;--i) //逆对角线上     {       if(a>'z') a-=26;       mapp[i][n-i-1]=a++;     }     for(int i=0;i<=n-1;i++) //最右一列     {         if(a>'z') a-=26;         mapp[i][n-1]=a++;     }     for(int i=0;i
