Kant, maybe. Hume is easy enough to just read directly. Hume and [post-tractatus] Wittgenstein seem like the only two philosophers I've encountered that are so easy to just pick up and read.

Aww.

Well I'm a little surprised but I probably shouldn't be, there's a lot of ways to implement lists.

> [1] = These operations rely on the "Amortized" part of "Amortized Worst Case". Individual actions may take surprisingly long, depending on the history of the container.
Just not a good use-case for lists.

I don't know the intimate details of python's implementation of lists. Maybe append isn't O(n) for python but I'm 99% sure it is. By "cons" I mean append to the front. E.g. a cons [b c] = [a b c] whereas append a [b c] = [b c a]. This is constant time.

I think you're going to need a hash table or a tree. If you have a custom sort anyway maybe the tree is the right way to go, which would make your routine something like O(n log n) depending.

wow thanks

>>5665785
oh I think I remember you from the other day. Is this where you were reading two files and creating a list of unique entries? That's always going to be a shitty algorithm without trees or hashing to speed things up.

>>5665781
the very first thing I saw was append, which is O(n) on lists, which makes the routine (as far as I glanced) O(n^2). Is the order important? You should cons to the front and, if necessary, reverse once at the end, instead of appending.

Obviously I repeatedly apply the successor function to 7 and 0 because that's what numbers really are, right?

He only thinks he's belittling anyone. Don't sweat it.

Though here's a math chick.

>>5665650
Actually I guess it trivially contains other irrationals such as pi-3, pi-3.1, etc. Meh.

>>5665715
It's not called anything to my knowledge. In base b it is just b-1.

>>5664536
I don't actually know whether she knows anything about math.

>>5664563
Obviously the decimals of pi contain pi. It starts from the first digit and runs all the way through.

It doesn't contain any other irrational, though.

>>5664437
Why, has he given three proofs of the Collatz conjecture or something? I've watched a lot of his videos, seen nothing untoward.

we have a whole board for shitposting, you don't have to do it here.

Um, no.

>>5664363
no, it's not officially released yet (last I checked)

>>5664324
well the hard math is more in terms of how to generate the numbers, not what to do with them
