Complete agreement. I decided. Using the debug all turns out, but tests are not the same. And I do not understand the example in the description. Why did you move 5 and 9?

done.

.toFixed(2) will always round 1.555 to 1.56.

I have had one too many sleepless nights trying to solve g964's various mathematical riddles.
When you start one of his challenges, you'd better have lots of free time in your disposal.
Having said that, I tend to agree that this kata is just a bit too much for a 7kyu.

You don't need to convert numbers. You can also do it with integer modulo and division (although that's a bit more tedious to write). And you don't need to keep any lists, sorting, etc. Just keep track of the largest number as you do each rotation step.

It is nice but mine is faster ;)
You can usually find a faster solution than the terse ones, plus I understand them better.
Some of the regex ones are crazy fast though, but some are slow (and I only js in the browser, so this environment is another variable, for me anyway)

This really doesn't seem kyu7 difficulty to me. At least not for JavaScript. kyu7 is a beginner tier. This is deceptively complex and requires caching results, type conversion, custom value based sorting, and a decent amount of manipulation. Add in the fact that the description is implicit instead of explicit for things like including the original value in the sort options and you are just going to frustrate someone who is at a kyu 7 skill level currently. This should be at least a 6.
