i knew it should be something like this but i just can't wrap my head aroud it. nice one

Really nice solution. It's always a pleasure to learn from others with more skill - bravo!

this is literally so hot

Couse I solved it Ai and after I did it without sorted Ai solved this with sorted

Cool way of doing that. In my answer I used a tuple instead of a dictionary so I didn't have to sort it later on. Both ways work.

why do you think he used AI?

smart

To be fair, I was working on this, and while it isn't "needed" I think the python doesn't guarantee what order keys are stored in. A dictionary uses hashing internally afterall! in my own solution I used reversed for a very similar purpose to this guy's sorted.

agree to disagree. As I see your point of view valid I also think of it like this: Ok, I know how to permuate a list with itertools, but it's crucial for me to know what exaclty permutation is and how the alghoritm look like

Couse there is no need sorted

I think u used Ai Bro

What do you mean by chunks? Chunks variable in his code is a list, which you also used for the same purpose in your code.

I totally agree. There is also another kata which suffers from this: Matrix Determinant (4 kyu).
