Description

给定两个整数M,N,生成一个M*N的矩阵,矩阵中元素取值为A至Z的26个字母中的一个,A在左上角,其余各数按顺时针方向旋转前进,依次递增放置,当超过26时又从A开始填充。例如,当M=5,N=8时,矩阵中的内容如下:
   A   B   C   D   E   F   G   H

V W X Y Z A B I
U J K L M N C J
T I H G F E D K
S R Q P O N M L

Input

M为行数,N为列数,其中M,N都为大于0的整数。

Output

分行输出相应的结果

Sample Input

4 9

Sample Output

   A   B   C   D   E   F   G   H   I
   V   W   X   Y   Z   A   B   C   J
   U   J   I   H   G   F   E   D   K
   T   S   R   Q   P   O   N   M   L
