Why was 6 afraid of 7? Because 7 8 9! Given a string apply the following transformations: If there is a 6 next to a 7 remove the 6 (6 is afraid of 7) If the sequence "789" appears remove the 8 and the 9 (7 ate 9) (If I'm not mistaken it doesn't matter what order you do the transformations in...

I rate my hat 5/7

I has 2 hats now :)

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ Well I'm sad to learn that there are now 5 people with Onion Knight hats

But I'm still proud of my secret hat

EEEEEEridan

@CᴏɴᴏʀO'Bʀɪᴇɴ Well "three" has an e in it so your number is sinful :P

@Ampora told me to make an account called EEEEEEridan so I did

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Ah. Close enough ^_^

EEEEEEridan

I wonder if it would be harder to completely avoid the letter e or have to use it in every word

Cᴏɴᴏʀ O'Bʀɪᴇɴ

The latter

EEEEEEridan

I think so as well

Eye agree*

Cᴏɴᴏʀ O'Bʀɪᴇɴ

in case you're wondering how i managed to get a result of (3 False)/2, i accidentally typed (3/2)(ln(19/3) = (3ln(19)/2) - (3ln(3)/2). playing "spot the missing close-paren" tells you that there should be one right before the =. it tried to correct by putting one all the way at the end of my input, so it got (3/2)(a false statement)

totally my bad, but funny

Using WolframAlpha usually ends up with me getting progressively more and more frustrated at its attempts to be "smart" until I just end up inputting Mathematica expressions into it, thereby defeating the purpose of using WolframAlpha

undergroundmonorail

@FlagAsSpam yeah you got there like two steps ahead of me :P ty

If you integrate the coefficient of e^u, you can find it easier. ;D

@undergroundmonorail You know that ∫(u')du is u+C, so finding the integral of the coefficient of e^u (the u' in u'e^u) will help you solve the integral.

I like how the hats take a second to load after a message is posted.

quartata

I mean, Pyth is a golfy version of Python

Perl is golfier than Python

flawr

The only good thing about a Perl golfing language is that it cannot get more unreadable.

quartata

6:57 PM

So

@flawr Oh just you wait.

undergroundmonorail

@FlagAsSpam in this case i already know the integral of the coefficient is u, don't i? i actually started with ∫4x^2e^(5x^3+9) and had to change it to (4/15)∫(15/4)4x^2e^(5x^3+9) in order to get the coefficient to be something helpful for me

@Doorknob冰 You look so frosty.

FlagAsSpam

@AlexA. You know, right?

Alex A.

Challenge idea: Given a number n, compute the first n terms of the following sequence. For an integer i, count the number of times one must factor i, join the sorted factors into a string, parse as a number, etc., until the result is prime.

@FlagAsSpam I know all. That is, except for what you're asking.

function f(x::Integer)
    x > 1 || return 0
    n = x
    i = 0
    while !isprime(n)
        p = sort(collect(keys(factor(n))))
        n = parse(Int, join(p))
        i += 1
    end
    return i
end

That's the Julia reference implementation for my challenge idea.

It might be too simple to be fun.
