Image Enlargement

Given an image consisting of $n$ rows and $m$ columns, where the character in the $i$-th row and $j$-th column is denoted as $s_{i,j}$, your task is to enlarge the image by a factor of $k$. That is, each character is replaced by a $k\times k$ block filled with that character, so that the resulting image has $kn$ rows and $km$ columns.

For example, if you are given the following $4\times3$ image:
( \begin{array}{ccc} % & % & % \ & & $ \\ @ & w & @ \\ ! & ! & ! \\ \end{array} \)
and $k=2$, the enlarged image will be:
\( \begin{array}{cccccc} % & % & % & % & % & % \\ % & % & % & % & % & % \\ $ & & & & & $\\$ & & & & & $ \ @ & @ & w & w & @ & @ \ @ & @ & w & w & @ & @ \ ! & ! & ! & ! & ! & ! \ ! & ! & ! & ! & ! & ! \ \end{array} )
Your program needs to produce this enlarged image based on the given inputs.

inputFormat

The input consists of multiple lines. The first line contains three integers $n$, $m$, and $k$ ($1 \leq n, m \leq 100$, $1 \leq k \leq 10$), representing the number of rows, the number of columns of the image, and the enlargement factor respectively. Each of the following $n$ lines contains a string of length $m$, representing a row of the image.

outputFormat

Output the enlarged image with $kn$ rows and $km$ columns. Each character from the original image is expanded into a $k\times k$ block, and the blocks are printed in the same order as the original image rows.
