fill the dots on the table above with 1 digit numbers, so:
Number in every cell = last digit of (sum of its neighbors (including diagonals))
or
Number in every cell = The remainder of the sum of its neighbors divided by 10
Here are the examples
[0,1,6,4,8] [1,2,1,3,2] [1,0,9,0,1]
[4,5,6,0,4] [4,5,1,0,9] [6,5,9,5,6]
[4,4,0,6,6] [3,3,0,7,7] [5,5,0,5,5]
[1,0,4,5,1] [1,0,9,5,6] [9,0,1,0,9]
[2,1,4,4,0] [8,7,9,8,9] [4,5,1,5,4]
