tf?

There are also even tools for making your own solutions in this style: https://pointfree.io/

It's not very odd, by Haskell standards it's rather benign ;-)

Here's what's it all about: https://wiki.haskell.org/Pointfree

I wonder why its written in such an odd way. Are you people just flexing on me with your hasklel skills? Or is there an actual reason?

short solution, but looks slower than I would like.

mus is a really funny name for the reverse of the sum

Well, how would you make it better?

Because of type safety! Rust's compiler is smart enough to get to the simple inclined forumlas

omg this is so smart. I didnt even consider using tuples like this!

Yes it does return a mutable reference! But since the solution stores that in a variable, the variable needs to be marked as mutable too! Otherwise we cant mutate the value behind it :3

Very funny solution...

I didnt know "scan" existed. Very cool method and good use of it!

I appreciate the effort and idea behind it. Why though
