see last comment :-), kata will be withdrawn

That's hard, I never thougth to search the internet if anybody already had this idea :-), but you're right, with this information this kata makes no sence and I will withdraw it.

Thanks for your feedback!

Hi, thanks for your input - added an additional line to explain what the tests are doing, hope that matches you point

Hi, thanks for your input - class name corrected

Hi, thanks for your input - randomized tests added

Great Kata, took me a long time to figure out how to solve until I found something about DFA and regular expressions, but I learned a lot!

In Kotlin the preloaded code names the function 'magic_show' while in the testcases call 'magicShow', I guess this was not meant as the first magic trick which has to be solved :-)

Woow, this took me weeks to find a solution which was able to fullfill the timing constrains. I was very keen on seeing the other solutions since a 6kyu should not be such a big thing. I am really suprised now that most solutions are working with my very first approach, which I never got running :-(.

Anyway, it was really much fun to get through this!

Like 'Floating-point Approximation (III)' I did not figure out the math behind this kata, so I was very suprised to see how easy the solution could have been. But anyway, also without knowing the math behind there are way's to find a proper solution and in doing so I even learned more :-)

Great kata, liked it very much :-).

I am still puzzled how to return a list with indices of type Long in Kotlin. I only found a solution for Int and all tests are passed, looks like there is no test using the complete range of n. From my point of view, n has to be Int. Any suggestions?
