I believe it is better to change 'i' into '_' since 'i' is not used after again.

owo recursive, nice

I'm still new to slicing in python. This solution has a couple great examples. Thank you. I appreciate it.

you will know later to never change the inputs given.incase u need to then make a copy of them

The res variable is unnecessary I think since the signature variable can definitely be used for the tribonnaci operation and for the return with some rejigging

Beautiful. Any suggestions(anyone) on getting better at thinking more like this. Having some mental blocks lately.

bruhhhh why i didnt think like this

Good point

People commenting you should have stored strings over lists are dumb.
You should have put the same number in your adjacents dictionary though.

That way you can write: "adjacents[observed]" instead of "adjacents[observed] + [observed]"

TIL theres a built-in sum function.

I'm new to Python...

hahaha

you guys make me feel stupid lol. that's a great motivation to work harder.

Goddam that's nerdy
