I don't write a ton of javascript and I don't offhand know for sure the syntax for instantiating such a thing.

I just looked it up and for n x n you have to create an array and then iterate over it creating new arrays to put in it? Seems a bit lol. I'd have done it like that eventually if being interviewed, but I would have been certain there was a simpler way to do it and that I was going to look like a moron.

In a lot of languages, for instance C#, you can create actual 2D arrays:

So I'm not sure I'd call arrays of arrays "fundamentals". They're a data structure only useful in some languages.

I looked up your original posts about it and if you're talking about the guy who created two 1D arrays and was populating them, then yeah, lol at that.

How would you do it in other languages? It's super simple in javascript.

So I've just started job searching on sites like Monster, indeed, etc. Which companies ads should I avoid? There doesn't seem to be a "master list" of job recruitment agencies to avoid. The only way you know to avoid them is if you already have the name. The list of names I've come up with so far is short... a list of 2: CyberCoders and Robert Half. When I put in a job title of "web developer" on Monster, somewhere in the range of 50-75% of the job postings were by CyberCoders (what I assume to be fake job postings since they seem to be pretty famous for that).

Fair enough.

Seems to me, FWIW, that you have a "big picture" idea and you want to refine it to the point where you can feel confident in proceeding with code development. If so, this is more in the realm of developing an architecture in my view. For instance you mentioned multi-threading in another post. How do you know you need that? Maybe multi-processing would be better? Could you possibly model algorithm's in Python and then implement them in C++? How will data flow through the system in an efficient manner? Maybe some off the shelf software could be used. I am just throwing out things to consider FWIW. Akin to architecting what the stream and platform providers did.

I don't think you are out to rip anyone off.

if you are looking for contract work (it doesn't appear that you are) I would do some research on the agency you'd be working through. There are plenty of slime ball ones out there. Others may disagree but principals only is one way to know that you know you are dealing with the company directly. Of course LinkedIn would work.

Stop wondering, competent people flub interviews even if the person is asked to code in a more natural programming environment than on a whiteboard. I have no data to to back this up but I would think that recommendations from developers you know to competent are much more reliable than how someone codes on a whiteboard in an interview in predicting success as an employee.

See the C# example I posted. Arrays of arrays can be declared in C#, but they're useless since we have true 2D arrays.

Edit: Should read int[,] arr = new int [n,n]; before someone calls me out on that :P

A different CyberCoders recruiter sends an email to our [email protected] email monthly.

Are you in the Northeast or is CyberCoders everywhere?

Avoid Robert Half. If you are in Boston area I can suggest the good ones.

At this point I really don't care what part of the country it is.

As far as I can tell, CyberCoders just mass spam ads for every and any city they know of.

Robert Half has been fine for me (in that they're just as terrible as every other recruiter). Got my last job for me and I wouldn't have got it without them.

As far as JS and fizzbuzz I'd prefer to see something like:

Doesn't print the number for non-multiples of 3 or 5. You could change it to:

I think as long as one of them is prime it works. It only fails when both numbers have a common factor – like 4 and 6. If you take out the common factors, then multiply what's left – the single expression works again.

lol forgot that nice work me

Yeah that's the one. The people who work with him swear that guy's a really good programmer. How is that possible?

This was a very low-pressure interview. We're all very friendly. We desperately need good developers, so we had a strong incentive to hire him. It was in the second half hour, so presumably he should've calmed down and gotten less nervous by then.

I'm just honestly curious if it's possible that a good developer could've failed the task of creating a 2D array that badly. If so then I feel like you have to question everything about the current standard process for interviewing programmers. Maybe there's some kind of market inefficiency – where good developers are slipping through the cracks – that could be exploited here.

I realized I never wrote fizz-buzz in Lisp. Here's Clojure:

It might be better just to define a isPrime function that returns true if the number inputted is prime. Use that to determine what to do in the first if statement.

If you're not a fan of if-if else-else you could just combine everything into one long ternary statement.

Agree with this (except for the error that was pointed out), the divide by 15 thing tilts the **** out of me. Should put it in the "things that shouldn't piss you off, but do" thread. I'm getting really heated right now.

Ruby:

ew and then you go and use a while loop in ruby instead of iterating over a range?

philistine.

A while loop in this case is a bit un ruby.

1.upto(100) do i

Anyone have recommendations for good intro videos for Strala and/or functional programming? We're using it more at work and I'd like to be less dumb about it.

My first programming interview ever had fizzbuzz, I pretty much wrote Suzzers first approach and expected to get shredded for it not being "pretty" enough, but he went on to tell me most people cant even get a correctly functioning one written, so style wasnt as important.

He also added on to it after you write it by telling you each if condition takes 2 seconds, so optimize it, which is a decent enough addition to a stupid problem. I passed with flying colors apparently and immediately got the job, so yay other people being not so great at programming? I still dont really get how a "programmer" cant throw together anything operational for it, weve already seen quite a few in the last few posts alone. But he shows me every fail, so I guess it is true.

javascript

for(var i = 1; i < 101; i++)
{
var ans = (i % 15 == 0) ? "fizzbuzz" : ((i % 3 == 0) ? "fizz" : ((i % 5 == 0) ? "buzz" : (i)));
alert(ans);
}

Nested ternaries are so fun to stumble across when trying to parse and debug someone else's code.

As the resident complete software noob who doesn't appreciate or know the differences between all the various languages, is c++ just super simple to do multi-dimension arrays or something? I can't even comprehend not being able to do such a thing with even a tiny amount of info, so I just assume there must be a language difference I don't understand.

Or I'm not getting what it is suzzer wants.
