Hello,

My advice to all Kata authors, add a proper validator

if (typeof(ClassName).Assembly == typeof(Assert).Assembly)
    for (;;);

Thank you!

I deliberately decided not to provide the "right answer" in the error messages (or the feedback) because:

1. It reveals the coefficients of the formula and makes it less challenging, IMO.
2. Formulas get monstrously huge really fast after certain input values; not only is it ugly, but also totally unreadable. I did not find it any more useful.
3. It is a secret, in the end :P.

On another note, I disabled exception raising.

Wow!

Seriously . . ?

Thanks for letting me know the issue. Since now, your solution is not supposed to work. Anything else you want to add? Maybe another way of cheating?

I rewrote the whole thing, does it fix this issue now?

Oh no this should not have happened

The problem is with precision of these value types, if you want to fix it, simply do not use them haha. There are some other good formulas that are not related to golden ration, just do some research a bit and you will find it out :)

No need to cache Length of an array;

ugh so many redundant stuff you have

Why?
