I wish I could see this solution.
It contains the line "if x == 704 | x == 681319 | x==681320", so you are not missing anything deep.
Changed test suite to deny this "solution"
703 not working
This solution only tests for divisibility by 9, not whether the number is a Kaprekar number.
this is no more coding but ...............
this fake solution ,take the advantage of system
Sum the numbers on the main diagonal
02 - Vector Variables 4
Area of a triangle
Vectors counting by 2
Flip the bit
Cull vector elements that contain a specified digit
Figurate number triangle
