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
Return elements unique to either input
Remove the two elements next to NaN value
Find the logic
Cull vector elements that contain a specified digit
Figurate number triangle
Maintain shape of logical-index mask
