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

There is a very interesting solution that is create 7 segement 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 segement coordinate on your matrix you can automate other solution in this group easily.
So i can call it is a master solution
