To be successful in your career, you need to be flexible and have a broad set of skills - the sort you get with a CS degree :) If you do only on mobile dev or only on web dev, you're limiting your success. It's totally OK to focus more on one than the other though. There are more jobs in web dev...
If you want to work in data science you should get at least a masters if not a PhD in a field like machine learning.
What exactly do you mean by 'web dev' and how is it different to software dev? Most people would consider web dev to be a subdiscipline of software dev.
99.9 here without tutoring, friend got 99.95 also without tutoring.
Work on understanding rather than memorising, but memorise when necessary/faster. This is what is meant by study smart not hard. Do questions that are at a much harder level than the HSC, because that way HSC questions seem...
Trivial for n=1.
Suppose the property holds for 1..n-1.
For general n, if their sum is divisible by n, then their sum mod n is 0. Take all elements mod n. If all elements mod n are 0, pick any subset. Otherwise, pick out an element x mod N which is nonzero mod n. 0 <= x < n. Of the...
I don't think this statement is quite true. Specifically, the "input comprising itself" bit - I don't know of a proof that shows that this is the case. If you're alluding to the diagonalisation argument, the result is slightly more complex.
Suppose that A is a Turing machine that given any...
First year at UNSW is C, not Objective-C. I don't know of any university which would teach Objective-C as a first-year subject. It's a relatively niche language.
I'm a professional C++, Java, and Python developer.
Python is probably the friendliest beginner's language. It's the one I started with and I can't imagine starting with anything else. The biggest problem with Python as a first language is that Python is too easy -- it hides what's happening...
2-3 months of casual learning probably isn't enough to get you work experience. Most tech companies won't even hire students after first year for internships because one year of study isn't generally enough to be productive in a company. Learning a programming language won't teach you to be a...
This is really wrong. Ignore all of it.
The vast majority of computer scientist graduates go on to become software developers/engineers. Some become researchers, data scientists, test engineers, product managers, etc. "Quality control technician" would not be a suitable position for a CS...
Google and Microsoft internship programmes are highly competitive and 'chances' don't really come into it. If you're smart, you're a great engineer, and you interview well, you'll probably get an internship. If any of these things aren't true, you won't.
Microsoft and Google are both close to...
This is such a bad question... I'd probably say probably unbiased because I'm guessing the question-setters aren't expecting you to read too deeply into the motivations of the librarians. I think they want you to decide if the experimental setup is fundamentally unbiased, which it's not. I think...
This is misleading at best and incorrect at worst.
UNSW, USyd and ANU are all FAR better than UTS at computer science. Ask any student, or look at the ATAR cutoffs, or which companies the graduates of each university go to. They are equally ranked in the "101-150" category in the 2014...
We can't help you unless you post your code buddy. It's like asking "what's wrong with my working out for this maths question" without posting your working out. Stop asking until you post your code, or at least a relevant sample of it.
I did SDD. Railroad diagrams and EBNF don't describe data structures, they describe languages (sets of strings).
EBNF can't be used to define a for loop or define a while loop. It's used to define the syntax for these constructs. Like, you might describe the syntax for a while loop as
while =...
The Uniball Jetstream 0.7mm (specifically, the lidded one) is a thing of beauty. It's perfectly weighted, writes beautifully, and rarely smudges. In my HSC year I would order them off eBay in bulk.
