Test if the input is a Kaprekar number: http://mathworld.wolfram.com/KaprekarNumber.html. Return a logical true or false.
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
Add two numbers
01 - Scalar variables
Find the 9's Complement
Factorize THIS, buddy
Maintain shape of logical-index mask
Increment a number, given its digits
Cull vector elements that contain a specified digit
