Q: Calculate the inverse totient function

Euler's totient function is defined as the cardinality of the set of positive integers less than or equal to n that are relatively prime to n. Given the positive integer m, calculate the lowest possible number n such that φ(n) = m. For reference, the series of this function is OEIS A032447. Th...

Downgoat

I sympathize with the intent, but I'm not sure that explicitly calling it a vote makes this less misleading, particularly since there's currently no easily-obtainable record of these "votes" the way there is for real votes (consider that a user with 20 rep would be able to find all of the posts he'd upvoted in his profile, but would see anything "downvoted" suspiciously absent in spite of the claims that they are remembered). I suspect it'll be hard to avoid problems in a terse message without actually changing what anon feedback does... — Shog9 ♦ Dec 26 '15 at 20:52

Well actually Cython does its type annotations slightly differently, but it's the same concept

quartata

Cython can use those annotations when in pure Python mode but in actual Cython you use cdef or cpdef

Pavel

What is this Cython you keep talking about.

Downgoat

@Pavel lower level derivative of python

quartata

Actually cython is a superset of Python

Pavel

So, should I switch to it right now, or could it break things?

quartata

2:45 AM

It just adds some interactions with the resulting C on top

Downgoat

But it is still lower level no?

quartata

@Pavel Don't it isn't usually worth it

@Downgoat I mean not especially

Anonymous

@Downgoat Not quite. Cython code, when run on regular Python, acts just like regular Python code. When it's run on Cython, it has several differences (static typing, for one), can be compiled to C, and often is faster than pure Python.

Downgoat

Does it always compile to one C file or can there be multiple?

x z != x (z) is what I'm saying

it doesn't say anything about (x)z there

basically I see all those variables as functions that take functions and return functions, right? so x(z) is applying the function x with the argument z

Qwerp-Derp

aditsu

no, it's (E1 E2) and the rest

Qwerp-Derp

@aditsu Oh that's what you mean

Ah

So in your output x(z) = xz

I thought x(z) was saying that z was in another group

This feels kinda creepy... is this legal?
