You are given an $h\times w$ 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 $s_1,s_2,...,s_h$ be $h$ strings of length $w$ that satisfy the following.

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

Print $s_1,s_2,...,s_h$ in order.

Input

The first line contains two integers $h$ and $w$ — the width and the height of the matrix $A$.The next $h$ lines contains the description of the matrix $A$.

Output

Print $h$ lines. The $i$-th line should contain $s_i$.
