Given a x-by-x matrix filled with zeros (x is odd and > 3). Use 8s to draw a number 8 into it! Like this:
x = 5, y =
8	8	8	8
0	0	0	8
8	8	8	8
0	0	0	8
8	8	8	8
x = 7, y = 
8	8	8	8	8	8
0	0	0	0	0	8
0	0	0	0	0	8
8	8	8	8	8	8
0	0	0	0	0	8
0	0	0	0	0	8
8	8	8	8	8	8

There is a very interesting solution that is create 7 segements on your array like a "7-segment Display"

This way may seem more complicated but once you has the data of segements' coordinate on your matrix you can automate other solution in this group easily.
So i can call it is a master solution
