Problem 3. The Cow-Signal

USACO 2016 December Contest, Bronze

Bessie and her cow friends are playing as their favorite cow superheroes. Of course, everyone knows that any self-respecting superhero needs a signal to call them to action. Bessie has drawn a special signal on a sheet of $M \times N$ paper ($1 \leq M \leq 10, 1 \leq N \leq 10$), but this is too small, much too small! Bessie wants to amplify the signal so it is exactly $K$ times bigger ($1 \leq K \leq 10$) in each direction.

The signal will consist only of the '.' and 'X' characters.

INPUT FORMAT (file cowsignal.in):

The first line of input contains $M$, $N$, and $K$, separated by spaces.

The next $M$ lines each contain a length-$N$ string, collectively describing the picture of the signal.

OUTPUT FORMAT (file cowsignal.out):

You should output $KM$ lines, each with $KN$ characters, giving a picture of the enlarged signal.
