Problem Statement

There is a grid with $N$ rows and $N$ columns. The cell in the $i$-th row from the top $(0 \leqq i < N)$ and the $(0 \leqq j < N)$-th column from the left is denoted by $(i, j)$.
For each $i,j (0 \leqq i < N, 0 \leqq j < N)$, the information of cell $(i, j)$ is given by a character $A_{i,j}$.
If $A_{i,j}$ is ., then cell $(i, j)$ is white, and if $A_{i, j}$ is #, then cell $(i, j)$ is black.

You are given a positive integer $K$. Enlarge the original grid by a factor of $K$ both vertically and horizontally to create a grid with $NK$ rows and $NK$ columns.

Formally, output a grid $B$ with $NK$ rows and $NK$ columns that satisfies the following.

• For all $(i, j)$ such that $0 \leqq i, j < NK $, $B_{i, j} = A_{\lfloor i/K \rfloor, \lfloor j/K \rfloor}$ holds.

Input

The input is given from standard input in the following format.

$N$ $K$
$A_{0, 0}$$A_{0, 1}$$\cdots$$A_{0, N-1}$  
$A_{1, 0}$$A_{1, 1}$$\cdots$$A_{1, N-1}$  
$\vdots$  
$A_{N-1, 0}$$A_{N-1, 1}$$\cdots$$A_{N-1, N-1}$  

• $N, K$ are integers.
• $1 \leqq N, K \leqq 10$
• $ A_{i,j} $ is . or #.

Output

Output the grid $B$ with $NK$ rows and $NK$ columns that satisfies the problem's conditions, in the following format.

$B_{0, 1}$$B_{0, 1}$$\cdots$$B_{0, NK-1}$  
$B_{1, 0}$$B_{1, 1}$$\cdots$$B_{1, NK-1}$  
$\vdots$  
$B_{NK-1, 0}$$B_{NK-1, 1}$$\cdots$$B_{NK-1, NK-1}$
