Q: Number of numbers from 1 to 100 where three numbers from 1 to 100 cubed equal n

Bgil Midol From numbers from 1 to 100, count the numbers where the following equation is satisfied with \$1 <= a <= 100\$, \$1 <= b <= 100\$, and \$1 <= c <= 100\$: $$a^3 + b^3 + c^3$$ I have this: def has_power3(n): for i in range(1, n+1): for j in range(1, n+1): for k in range(1,...

Q: Find the third biggest integer of an array

antonio-erickHow can i make this work with fewer lines? The goal here is to get the third biggest integer of an array. I would also appreciate if someone polished this code. let array = [442, 93, 3, 5, 30, 10]; const f = (arr) => { let secureArr = [...arr]; let big0 = Math.max.apply(null, secureArr...

Q: Small Scheme Interpreter evaluating operators?

TheSinisterStoneI'm writing a mini-Scheme interpreter in Java, and everything works well right now. Though, one part is driving me slightly insane because of how it looks. I'm constructing an AST for each type of expression in Scheme e.g., applications, defines, cond, if, lambda, so on and so forth. The applicat...

@Duga Not sure about that one - it looks like it's adding code for review, which might be better in a blockquote. But does it need to be in the question at all?
If your code works and you just want someone to review it and come with suggestions, please post it over at Code Review instead. — M. Eriksson 7 secs ago

Q: This code transforms a normal map into a 2d gradient field and then iteratively integrates it to a likely solution. C++/CUDA

Niklas HauberI don't have a lot of experience with C++/CUDA yet and would appreciate some advice mainly on the code style specific to C++ (I come from a C# background). Any advice on increasing performance would also be appreciated (using shared CUDA memory comes to my mind and I might implement that later). ...

Questions asking how to improve successfully-running code are too open-ended for Stack Overflow's remit. This question might be appropriate to codereview.stackexchange.com, but read their help first to be sure it's on-topic and that you form the question correctly. — T.J. Crowder 58 secs ago

@Peilonrayz It lost a couple hundred points again.
@TobySpeight It's a bit iffy indeed, but if I read the answer the original question wasn't particularly clear either.
@SᴀᴍOnᴇᴌᴀ I don't know what OS he's running, but most have the option to have multiple (virtual) desktops inbuilt. OpenSUSE had it almost a decade ago already and Win10 added it a year or two back.
Sometimes I'm at 5 at work, although it only works if you stick with 1 application per desktop. Trying to open Excel on 3 out of 5 will give you a bad time when opening/closing files since it's going to switch instances in an unhelpful way.

Q: Is using abbreviations for frequently used long type names acceptable in production code

AlwaysLearningIn a particular module, I find myself writing string::const_iterator a lot. Some functions take four iterators as arguments and their signature becomes impressive indeed. In such a module, is it OK (in terms of coding style) to define using SCI = string::const_iterator; and use SCI throughout?

Please be aware that fiddling with a print statement until the results look right and then "saving" the output to a variable is not considered normal practice and would be rejected in a homework exercise or code review. You would instead be expected to format a string correctly using Python's many convenient functions for this, that can easily mimic what print does. — that other guy 14 secs ago
