Maybe you need to learn how to articulate an argument without resorting to the ad hominem? I'm not going to get in a pissing match where a bunch of people start throwing around credentials, most of which are of questionable veracity.

Anyone other than me still curious as to the answer the interview lady gave OP?
EDIT: Saw the edit in the OP. Bad question. Do you get to ask a vague one in return?

Umm, no, where you write the numbers makes it an array. It may not have brackets or what not, but it's still an array. The fact that he added carraige returns and spaces made it an array.
He replied in an earlier post. He said the answer was, "Use a compare function." A silly answer, imo, as the question seemed to focus on a description of how it would be in terms of OO vs. procedural, and distilling the answer to a simple function name says very little about understanding the difference, imo.
The OP said she said to use the compare() function. One part of the whole solution; definitely not a complete answer.
Ok. I'm just so sick of programmers and their syntax obsession.
Also, could someone please explain why the afore mentioned array wasn't 2d?
Descartes, just so we understand you properly... how many dimensiona is the following representation of an array, assuming each digit is a discrete element?
3 8 7 5 2
1 2 5 3 1
6 4 9 7 3
Is this a 5 dimensional array because it has 5 columns??? Or something else?
Just trying to understand your logic here...
yes, i got carried away with the hijacked discussion and forgot to read about the original problem
It's simply a fact that you are wrong about it not being a 2-D array. With most people I would have let this drop by now so I guess it is your snobbishness and attitude that lead me to repeating this a few times to drive the point home. The way those numbers were written was acceptable notation for displaying a 2-dimensional array in text format.
If you are still in doubt, go read up on it and find out. You don't need to come back to this thread and admit you were wrong, but at least know the definition of a 2-dimensional array if you are going to continue charging what you do for your work.
No, I really didn't choose to do so. My first reaction was erroneous as I was thinking of it differently at the time, I admit it, and now I understand what everyone was saying.
I'll say it: My mistake. Suggesting I don't know what a 2D array is is rather silly, and anyone that knows me should quickly realize that.
If the question were reworded it might be the right answer. Heh.
Something like, "You are writing an object and want to allow other developers who use the object to sort a list of your object using standard sorting methods. What do you need to minimally do to accomplish this possibility?"
Ehh... well that one sucks too, but I'm sure you could come up with something.

Sorry I said that. Your replies here usually display a high level of intelligence, so it surprised me that you were blinded by your first impression and unable to see what the person who posted the array had in mind.
I'm still wondering where you got a fourth dimension from.
Hmmm. Being an EE instead of a CE, maybe I'm getting my terminology mixed up. But isn't a 2d array an array of vectors? Or a single vector consisting of vectors as elements?
I'm thinking Matrix math, LU decomp. etc. Maybe for programming puproses you make no distinction.
I believe he was thinking that the numbers represented a single dimensional array of the size represented by the number...? e.g.
3 1 5
2 3 4
=
Array of size 3, array of size 1, array of size 5.
Eh, who knows. He was clearly thinking too far outside the box. That happened to me once... the new radiohead cd had just come out and someone told me "radiohead sold out" and I was panicking thinking I wouldn't be able to get the CD anywhere.
Vecor, Array, List, different names for the same thing iirc. (and of course what they are made of changes how you view it, you can have a vector of lists of strings, etc. etc.)
Well, if you look at the visual representation you can probably see what my brain chose to respond to it that way.
I can't honestly say why my mind chose to respond to it that way. I could make excuses and say I was thinking about other things, etc. but I'd rather just admit a mistake. It was a brain lapse, or whatever the hell else someone wants to call it; it happens.
So, I will offer an apology for my rash reply to those have responded in kind. To those that jumped onboard as a way to simply attack me I do not.
:thumbsup:
Semantically yes, but in some languages using some weird memory kung fu they actually store 2d arrays as single memory blocks and not in seperate locations. That is why if you traverse the 2d array going vertically instead of horizintally (or vice versa) when sorting, it can be somewhat less efficient.
You are correct. I'm actually taking a moment to think why that was my default thought process, because under normal circumstances it isn't. When I finally realized it I was a little disconcerted to say the least.
Thanks everyone for the responses. Jbourne and Torpid cleared up the interviewer's answer for me, I really had no idea about the compare function you could write into objects. And Descarte's being a good sport, he already apologized for reading it wrong.
