题目描述

给定一个$H \times W$的矩阵$A$，其中$A_{i,j}$是$0$到$26$之间的整数，矩阵$A$的第$i$行第$j$列的元素是$A_{i,j}$。

现在我们希望找到$H$个长度为$W$的字符串$S_1, S_2, \dots, S_H$，满足以下条件：

• 当$A_{i,j}$为$0$时，$S_i$的第$j$个字符是一个句点（.），否则是对应的大写英文字母。（例如，第$4$个字母是D）

请按顺序输出$S_1, S_2, \dots, S_H$。

限制条件

• $1 \leq H \leq 100$
• $1 \leq W \leq 100$
• $0 \leq A_{i,j} \leq 26$
• 输入中的所有值都是整数。

输入

输入数据共有两行。

第一行包含两个整数$H$和$W$。

第二行包含$H \times W$个整数，表示矩阵$A$。

输出

输出$H$行。第$i$行应包含$S_i$。
