Problem 50887. Draw a '8' in a zero matrix!
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 8
8 0 0 0 8
8 8 8 8 8
8 0 0 0 8
8 8 8 8 8
x = 7, y =
8 8 8 8 8 8 8
8 0 0 0 0 0 8
8 0 0 0 0 0 8
8 8 8 8 8 8 8
8 0 0 0 0 0 8
8 0 0 0 0 0 8

There is a very interesting solution that is create 7 segements on your array like a "7-segment Display"
https://www.electronics-tutorials.ws/blog/7-segment-display-tutorial.html
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
