@kartikpatodi what are you trying to do? your second code returns a new instance of

A

and not an Integer

Sorry my bad actually i have to implement in the second code

@kartikpatodi first of all, i'd suggest that you work through https://kotlinlang.org/docs/tutorials/koans.html

@kartikpatodi this is a 4th kyu puzzle-kata, so this not made for beginners in kotlin. I'd suggest that you skip this kata and try to do easier katas

Yes i thought i could use reflection or something similar... Well anyways thanks

@kartikpatodi yes, reflection would be the way to do it
