Thanks for explanation and for help in this task. Best codeReview ever)

Your algorithm is very elegant (i think). Is this a specific technique, does it have a name?

It's an error in description

Couldn't reporoduce, just duplicated config object to Test Cases section

Just added random tests. I think 100 random expressions would be enough.
Next step is to improve description for the task.

Thanks for help

Where are duplicates? Could someone find at least one, please? I didn't, @dfhwze didn't, @JohanWiltink didn't

No specifics, only spatial reasoning

@dfhwze Why are you behaving like a child? If you want to help, do it. If you want to troll, find another place, please

About what you are talking to?

Let's focus on main topic of this thread.
First of all, as i said before - thank you for initiating this thread because you helped to extend functionality (btw i have to enhance documentation based on recent changes, thank you also).
Secondly, I searched through CodeWars as before and I think this evaluator slightly different and obviously not duplicated (if so, find it to prove your point).

18305 different tasks and maybe 20 about math expressions evaluation (more or less) and every task different in it's own way and every approach deserves chance to be published.

Thank you guyz for help and ideas. I added functions and math constants. Could you check it out?
I think it's much different expression evaluation task. What would you say?)

"Duplicate" is most difficult ISSUE. I'm working on it
