Thanks for the link, I read the problem more carefully and was able to solve it

There are some monsters. I can kill them with one punch. So I'll kill them. One punch and they're killed (all). How come there are more monsters then?

I know now what you meant, however imho it wasn't the best description we could get. I should say though that english isn't my native language...

You are strong enough to kill them with one punch, but after you punch 3 times, one of the remaining monsters will hit you once.

I'm hoping this part of description makes it more clear that you can't kill them all at once.

Ok, kill each monster... Sounds different than "kill them with one punch".

Added one

Added one

Done

You can kill each monster with one punch, but you can't hit more than one monster with a single punch.

I don't get it. If I kill all the monsters with one punch, what monster could punch me back then? Why would I need to punch more than once at all?

You must do something wrong. Please read this: https://docs.codewars.com/training/troubleshooting/

Why my code does not work there everything is correct and in IDE checked not 1 time and in codewars constantly subtracts 1 hits in the code though should not do it
