Problem Statement

You are given an $H$-by-$W$ matrix $A$ consisting of integers between $0$ and $26$. The element at the $i$-th row from the top and $j$-th column from the left is $A_{i,j}$.

Let $S_1, S_2, \dots, S_H$ be $H$ strings of length $W$ that satisfy the following.

• The $j$-th character of $S_i$ is a period (.) if $A_{i,j}$ is $0$, and the $A_{i,j}$-th uppercase English letter otherwise. (For instance, the $4$-th letter is D.)

Print $S_1, S_2, \dots, S_H$ in order.

Constraints

• $1 \leq H \leq 100$
• $1 \leq W \leq 100$
• $0 \leq A_{i,j} \leq 26$
• All values in the input are integers.

Input

The input is given from Standard Input in the following format:

$H$ $W$

$A_{1,1}$ $A_{1,2}$ $\dots$ $A_{1,W}$

$A_{2,1}$ $A_{2,2}$ $\dots$ $A_{2,W}$

$\vdots$

$A_{H,1}$ $A_{H,2}$ $\dots$ $A_{H,W}$

Output

Print $H$ lines. The $i$-th line should contain $S_i$.
