Problem 3. The Cow-Signal
Contest has ended.
Log in to allow submissions in analysis mode
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×N
paper (1≤M≤10,1≤N≤10), but this is too small, much too
small! Bessie wants to amplify the signal so it is exactly K times bigger
(1≤K≤10) in each direction.
Contest has ended. No further submissions allowed.
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.

SAMPLE OUTPUT:
