This was originally going to be a challenge for Code Golf SE, but first I wanted to see whether someone can figure it out without me telling so.
If a number conforms to a special rule, I call it a Sharp Number™. Find whether a number is "sharp".
|Sharp Numbers™||Non-Sharp Numbers™|
Note that each of the numbers can be tested individually; there is no pattern among different Sharp Numbers™
why is the flat log of the parts
don't fall down the axis!
