Yeah but then it wouldn't be a 1 line solution. 👀 Can't be having a best practice solution on Codewars that's more than 1 line long!

but if you gotta add two lines to import, is it really shortening?

any chance you can expand upon this? and maybe point in direction of a reference?

Dynamic Programming, not Number Theory.

Google the kata title, look on SO, read and learn. ( It looks like a gimme, but there's a twist! )

( Then realise that calculating Fibonacci by iterating [a,b] = [b,a+b] is Dynamic Programming, and finally get something of a handle on it. )

Yes it was. Same with filter.

wtf dude...

this site might be inspirational, but it's rarely a good idea to blindly copy code from 99% of the solutions.

Regardless of it being marked as "best practice" or whatnot.

Thanks :)

Knowing maths and algorithms probably is not how this person reached 1 kyu.

No, none of mine is more efficient. Just trying new things. :-D

No, SHA1 cannot be reversed. This solutions tries several attempts to recover (using brute force) the word from SHA1.
