Rejected, since issue already resolved.

Diff --> this line added to the description.

Passing float instead of integer to a function raises more likely TypeError instead of ValueError.

(see for example https://github.com/python/cpython/commit/f066bd94b9225a5a3c4ade5fc3ff81e3c49b7b32)

May be more interesting to switch to TypeError instead.

I don't know... The best solution, of course... But I think it would be nice to try at least to improve your skills in creating algorithms. If there a module it's good. But sometimes there isnt

The code is nearly identical:

Sir, you are nitpicking here :'-)

You are not going to spoil that much with an example yielding 2 or 3, especially due to the meeting difficulty being linked to nested brackets.

Recursion limit is 1000 by default in Python.
Given this limit, in worst situation, this solution can generate numbers up to (1000 - 3) // 6 - 1 = 165 bits.

However Python has also an undocumented limit on nested parentheses when trying to eval a string which is 200 only.

Seems like it has been solved by a mathematician <3. Sophisticated solution.

Not all kata are designed for interview.
If you expect all solutions to be prod-ready, you are not on the right website.

Here is a suggestion to learn from this solution: you should ask for explanations politely.
It may bring you more insights than complaining.

Slower but less memory
