@Riker That doesn't matter. You don't get to use your mod powers on a whim to edit others' messages (even feeds). Only when it's necessary should you use them.

@Pavel The previous times that mods have edited Feeds messages is when the post in question had already been posted and oneboxed in here, to save vertical space. Riker editing that Feeds message was pointless and an abuse of mod powers.

Wait, not toroidal? Dang, my solution doesn't work.

@Riker Denied.

Mr. Xcoder

@Mego Why doesn't ⌠ß▀π⌡╓ work?

@Mr.Xcoder Because of ß and ╓. ╓ makes an entirely new stack frame, without access to the outside frame's inputs.

Mr. Xcoder

oh... dang I have to use register right?

AdmBorkBork

7:13 PM

@Mr.Xcoder Yeah, it's because $a[-1] refers to the last element of the array.

...okay, @Shog9, I do like waffles with syrup

FlipTack

@Riker essentially, yes. There's an eval function to make it usable, and _ is printed at the end, but other than that it's just using symbols to create values

What do you mean by provide a standard Python version?

CMP: Should factorial(-n) give product(-1, -2, -3, ..., -n), product(-2, -3, ..., -n), or -factorial(n)?

@HyperNeutrino The first seems quite non-sensical, as it is not very consistent depending on the parity, i'd go with the last.

@Mr.Xcoder ok

@HyperNeutrino I was going to say Gamma(-n) but then I remembered that the Gamma function isn't defined for negative integers

:P

so I guess factorial(n) = Gamma(n + 1) = sign(n) * Gamma(abs(n) + 1)?

@Mr.Xcoder I have a 12-byte solution. I'm not sure if it's optimal.

@Mego What does ╓N do?

Nvm.

Anonymous

@Mr.Xcoder Retrieves the last element of the list returned by ╓ (which takes a function f and an integer a, and returns the first a values of map(f, count()) where the output is truthy)

Mr. Xcoder

Yeah just figured that out.

@Mego Yuppe 14 bytes \o/: ;╗⌠;╜¡'0@cY⌡╓F... any tips?

13 bytes.

I don't actually need the second ; do I?

Anonymous

One way to look at the challenge is to approach it from a generating function angle. You have a polynomial n = a_i * x**i + a_(i-1) * x**(i-1) + ... + a_0, and you want to find the minimum x where 0 ∉ {a_i, ..., a_0}.

Anonymous

7:43 PM

@Mr.Xcoder You don't need either of them

Mr. Xcoder

oh my god... Wouldn't that make it longer?

@Mego I seem to need the first one.

Compare this to this.

Anonymous

Why? <...>⌠<...>⌡╓F is the same as <...>1⌠<...>⌡╓

Mr. Xcoder

Oh duh... really right.

@Mego Wouldn't that return [N] instead though? Is that allowed?

I am confused now...

A: Default for Code Golf: Input/Output methods

Input and output of a single value may be represented as a singleton list For example, if the value was 4, [4] would be an acceptable representation (using Python list syntax).

I originally had 13 (the solution you also came up with plus i to flatten), which I used to make the test cases. I thought of an alternative that got it down to 12 without returning a singleton list.

It should be shorter than 12, but there's a bug or two in the base conversion code that makes it not work as it should

Is TIO broken?

Leaky Nun

@HyperNeutrino I don't think so

@Uriel @Mego also, gamma(1) = 1 :P

gamma(1) = int(x=0, infty, e^-x dx) = -e^-infty - -e^-0 = 1

Anonymous

@LeakyNun The Gamma function is an extension of the factorial function, so that's a chicken-and-egg argument

Leaky Nun

9:29 PM

@Mego but it isn't circular as the definition of gamma stands on its own

being the analytic extension of [int(x=0, infty, x^(n-1) e^-x dx) for Re(n)>0] to the whole complex plane

Anonymous

@LeakyNun The definition of a factorial stands on its own, too. Is Gamma an extension of factorial, or is factorial a special case of Gamma?

Leaky Nun

@Mego hmm...

Uriel

Well, x^0 goes the same way - x^0 = x^1 / x = x / x = 1
