Create The Scaled Picture
Create The Scaled Picture
Given the picture $n \cdot m$, built from black and white pixels. Your task is to scale it up, replacing each pixel with the rectangle $a \cdot b$, entirely consisting of the pixels of same color as the replaced pixel.
\InputFile
The first line contains four integers $n, m, a, b~(1 \le n, m, a, b \le 10)$.
$i$-th of the following $n$ lines contain the binary string of length $m$, describing $i$-th row of the initial picture. $0$ denotes the white pixel; $1$ denotes the black pixel.
\OutputFile
Print the scaled picture as the rectangle consisting of $n \cdot a$ rows and $m \cdot b$ columns.
