I found your objection here confusing until I thought about it.

Fundamentally, I agree. However, I think the underlying problem isn't the logic of planets leaving the system. That's a symptom. The problem is that the orbits change. As you note, if a planet leaves the system on the left, all other planets shift to fill lower orbits. However, if a planet is destroyed the same thing happens. The logic is consistent and solvable, but it's weird. There's a sort of extra movement built into it.

My biggest complaint, I think, is that the series didn't build upon itself. It would have been great if each new entry in the series added instead of being essentially the same with a different skin.

See above, I think the timing assessments are off by a factor of 10.

Yes, random tests Javascript

ffs, I thought I had fixed that... x/ Yes, it should be "propenoyl..."

random tests, I guess?

This one bothers me:

15-[1,2,2-triamino]propenanoyloxy-2,4,5,12-tetra[2-[[4,5,5-tribromo-1,4,6,7-tetrachloro]hept-2-enyl]arsino[1,2-diamino]ethenoxycarbonyl]hexen-3,5-diynylhexadec-10,13-diynoic acid

It has propenanoyloxy in it.

This has both an alkene en and alkane an suffix, before the oyloxy.

Yet, examples, such as 4-propanoyloxypentanoic acid and prop-2-enoyloxy..., never show this combination.

How do you explain propenanoyloxy?

In general

• Can any alkene, alkyne, alkenyne have an as additional suffix or only in front of oyloxy?
• In your summary, you sometimes use alk, sometimes alkan as prefix; What do you mean in these cases?
  • (alk) -> is this just a radical?
  • (alkan) -> is this a radical, with alkane/alkene/alkyne?

ester                 .                   (alkyl) ...oate
                      (alk)oxycarbonyl
                      (alkan)oyloxy

got it, thanks!

js fork approved

except the test is not on ans...

You should explain the math notations: not all users have a math-college background (hint: I don't ;) )

Also names are not to be chosen randomly. If you can switch the function name from sum_not_prime to sum_prime without changing anything else, this means the name has nothing to do with the task (or one of them is totally wrong).

read below...

Sorry, this is my first attempt at creating a kata. I don't understand what the problem is in my description. Maybe you can help me?

Definitely shorter, but not more readable IMHO.

If you want something that sort, but a bit more readable (and pythonic) you could use:

return ans if ans and len(ans) < 140 else False

Anyways, ans is never going to be empty because you already inserted '#'

The description still doesn't describe the actual task.

What do the mathy shenanigans mean?

also, sum_not_prime became sum_prime whithout any additional explanation: this smells absolutely bad for the quality of the description.
