That is a clever use of replace and split! Well done.

ocelot269 would benefit more if you would explain why it is inefficient...

If I knew that split() does a better job in removing " " * n than split(" ").
Well I guess that's why I here. To learn, I guess.

... check your damm '()'... I overlocked that there was a ')' missing in my print statements like so:
print(iter_pi(0.01 == [100, 3.1315929036]))
(I have tried to avoid the syntax error by adding a ')' at the end -fatal.
I assumed that my code was just too slow and surrendered.

Then I saw that there were proper solutions similar to mine.
After a short check I knew that my code was okay but my print not.

What a bad experience. Though not your fault ofcourse.

I think for a level 6 kata, performance should not play that a big role...

I find 5kyu overrated as well. It was fun anyway.

Polynomial regression is kinda overkill but works just fine

This one made me bite my tongue more than once....

What the O() ;)

something else. Great!

this code is not even stable...

format() would have been way easier... Anyway... now I know little about map() as well even though it was not asked here ^^ The map<String,int> in the description has confused me alot.

Impressively simple! I hopefully have learned something here!

I had a lot of fun with this little task. Thank you!

I would rather code this game alone
