Zero Padding
Computer images usually contain tabular format with integers
from 0 until 255 for 3 colors RGB.
For processing purposes sometimes zeros are added all 4 sides
of the image.
Question:
Write a program that
receives two integers k and j and a two dimensional array.
The program will add (k) columns of zeros before the first
and after the last columns of the image. And also, the
program will add (j) rows before the first and after the last rows.
Input specification
You will be given four integers (k,j, and m, n) at the beginning.
where m and n is the width and height of the array and
1 ≤ (m and n) ≤ 80 and 0 ≤ (k and j) ≤ 10.
On the next n lines you will have m integer numbers
where each of the number is between 0 and 255.
Output specification
Show the zero padded array.
The number will be space separated.
