From a question bank used by a multinational software company in recruiting trainee developers

They are really strong questions..... reminds me of Ms certification exams

airsaylongcon:
Why you dey run mouth? How many hours e take you to ask me your own?. I will modify this post with the question so look out

*modified*
A data structure is "built" using nodes. Each node has exactly two pointers that point to other nodes. None of the pointers is null. A C program is written to count how many nodes are accessible from any of the nodes in th data structure. The code use an "indicator" field (initialized to zero for all nodes). Correct the following code so that it works properly as it will not work in its current state

struct t (int i,m; struct t*b, *d)
int count(struct t*a)
{
If (a->m) return 0;
return count(a->b) + count(a->d)+1;
}

Are you getting these questions from past certification exams ?

asalimpo:
Yeah. Let's guess.
From the way you blab, you could be a transgendered man.
From your coding chops, you cudve been a recent programmer (1 - 5yrs experience).
From your crudity, a street kid or tout.
From your immaturity a teen or tween.

hahaha
Seriously, I don't think seuunthomas is a kid at all... I think he's a mature man and approaching old age. That's why i watch my words with him
He might sound erratic because the thread has gone too long. It happens to different people in different ways. For example if I personally am in a chess game for too long, I start making erratic moves that I never would make normally.

seunthomas:
People like you dont like criticism. Ok Mr YES guy, you are good and the BEST.

Except your earlier posts were joke, you have claimed severally you are the best. That was why I was expecting perfect codes from you, but it turns out, you make mistakes like everyone else.

And Yes, for once you are right about me. I do not like criticisms at all probably because I was surrounded only by people like you for a long time. (People that don't correct errors).

It's obvious you didn't go through the link I sent earlier. Please go through it, you are a good programmer, but you would be better if you knew how to correct errors without discouraging

seunthomas:
def run():
while True:
arraydays=[monday to friday]
if time!="6pm" and day not in arraydays:
sleep(till 6pm)
else:
print "Something"


Something like this. Its algorithm not working code sha

Now that's how an algorithm looks like, not the code you wrote

x=3;
function amADude(){
x=3;
amADude();


}

seunthomas, please don't take this the wrong way but you behave like an old man. (Expects everything to be perfect but makes the same mistakes)

seunthomas:
x=3;
function amADude(){
x=3;
amADude();


}

If dhtml was the one who wrote this, you would be the first to write BAD CODE smh

seunthomas:
Oya make i explain myself na before you crucify me. In programming especially in statically typed languages it is always recommended to declare every type before using it. Although code works fine but you did not define the type of i in your loop. Na wahala be dat ohhhh. It will work ohh but you may get segmentation fault or memory corruption.
What am i saying self. Looking at your code its very wrong........... You wont understand. IT WORKS ohhhh but ITS WRONG.....

You criticize people's codes toooo much, it's becoming annoying. The painful thing is you don't bother to correct the code you criticized. See an example of correcting people's code without making them feel bad or inferior https://www.nairaland.com/2529139/tic-tac-toe-online-game. People make mistakes

Consider that you have written 2 codes or so on this thread and every single one had a mistake or 2 so please correct people's code instead of just bullshiting it

guru01:
Write a program that computes the length of a given string with out using the inbuilt string length function of that language.

So disappointed in the simplicity of this question . Or are you simply just purposely under estimating your opponent ?

asalimpo:
I worked on something similar to 2, last year. The project is abandoned but the algorithm is in my head. It's not minimax though,
just me thinking and solving an exercise. I guess, when it's complete ,i'd have unknowingly re implemented mini-max (whatever its called).
The important test i had in my mind was to set to computer opponents to play each other.

If the game is unbeatable, then that's pretty good. I got the Mini-Max algorithm after long hours/days of stressing my brain. But due to the fact that my game is 12X10 instead of 3X3 in normal TicTacToe, Mini-Max alone is no longer feasible, I need alpha-beta pruning. And I find it just too confusing. I'll upload so u take a look

seunthomas:
public static void stdOut(s) {
System.out.print(s);
}

for(int i=1;i<9;i++) {
stdOut('I just dey run my mouth, page '+i);
}
In java your stdOut should be called like this
stdOut("I just dey run my mouth, page "+i);
Take note of the double quotes cause java is very strict.

function stdOut(s) {document.write(s);}
for(i=1;i<9;i++) {
stdOut('I just dey run my mouth, page '+i);
}
And though this is lexically correct in javascript it wont run, because it needs an initializer dom body load event or or some other event that would trigger it

Your java code is even wrong. It should be

public static void stdOut(String s) {System.out.print(s);}

not

seunthomas:
public static void stdOut(s) {
System.out.print(s);
}

Anyone can make mistake

seunthomas:
even the javascript version is wrong. And it wont work in java.

Why? because he didn't declare i ? sure it won't work, but common it's just an illustration naw. In the context he used it, it's not supposed to work cause it was a clear joke. Please just stop the criticism.

seunthomas, judging from some of your posts, you apparently have some experience, just that no single thing to show for it. It is understandable that against all odds, you have been on one company project to another ever since you started programming so therefore no time to do any personal thing. Well let me give you a task so you can at least have 1 open source project.

1. Write a script that sends a broadcast message to all facebook friends (I did it sometime ago but I had issues broadcasting links so if you can solve this, I would really appretiate)

2. Use MiniMax algorithm to make the AI of my Tic Tac Toe game unbeatable. (This is my real problem, I must confess, MiniMax Algorithm alone is tough enough. Then considering Alpha Beta prunin.... I just need external help).

This is also open to other programmers including dhtml. I'll put the game on GitHub and share the link

seunthomas:
You cant reach drag with me. You no sabi code. I cant smell it on you. If really you are coder it would show in your vocabulary.

looooooooool. Funny, but men, you look down on people tooooo much.

seunthomas:
Well though i quite respective all the views here. I want to state categorically that its challenges that bring about creativity and innovation. Its when there is an atmosphere of mature competition that we see progress. As for my beef with @dhtml18 its a mature way of stressing our mind. The drama just makes it more interesting. At the end of the day win or lose both of us should be able to appreciate each other. I think we need that in Nigeria rather than foreign hero worship, who knows we just might make some legends on this forum.

Wow so you can sound serious like this _(Y)

dhtml18:
@OP, you are just wasting your time here. The programmers on nairaland code faster with their mouths. . . .you go frustrate for here.

You are so right. All they do is hunt greedily for money and look down on other programmers

dazekid:
I understand your perspective on this but I can guarantee you that the person you quoted is spot on. Serious hackers(ethical or otherwise) need high performance hardware. Mapping ports using cain on a 4GB RAM system isn't even comparable with an 8GB RAM system, running through a dictionary list that is over 5GB in size is a futile venture on a low end system, heck you might even need to run various vulnerability testing software at once, whilst performing other exploits, low end systems aren't cut out for this.
I guess the issue here is most people are giving replies from a programmer perspective. The situation is different from a hacker perspective.

There are just more efficient ways to do such. Most people, (not only you) say a powerful machine is needed for hacking mainly because of brute-forcing or dictionary attacks. But trust me, my 16gb ram laptop has done more damage in a shorter time. It's all about your approach

Nice one mehn

seunthomas:
Actually i believe its because of guys like @maekhel @fincoapps that we dont have much development in software area. Apparently you are easily moved by mediocrity.

lol why ? because I know you've got nothing to offer ??.... Tomy .... interesting way of judging people

dhtml18, I suggest you just ignore him. I've come across people like this.... they'll never stop bragging. Don't expect any Github link, trust me you'll get none from him

Djade007:
@op just buy decent a laptop with atleast 4gb ram. Then you can upgrade it later by increasing the ram and swapping the hard disk with a ssd.

I would rather continue to dual boot Windows and Linux on my pc than to get a mac which is overpriced....

Macbooks are not overpriced. I noticed people that haven't owned a Macbook always say that though

rolexsms:
Correct ur date and time of your computer. And refresh the page... Good luck

hahahah exactly.... 2015 ?

Fulaman198:
I don't think I can ever get that angry.

I might put my hand on my head in frustration trying to find an error (which I eventually find). But never to the point where I smash my expensive machine. People need to think with the end in mind.

Lol true but it depends on my pc price. To me my PC is expensive and I once punched the screen because I spent the whole day trying to fix a div to the footer . Something I should be able to do while closing my eyes

ovoSoftware:
Sir pls which platform can you not develop on using the a mac, my first app (OVO Multimedia) was developed on a pc using eclipse infact i am currently typing from a pc.....so get your facts right, i use windows too.

8gb RAM slower than a 4gb RAM computer, there is something you are doing wrong, remember apple doesn't manufacture their hardware so the intel processor in mac is the same intel processor in hp (et al) what makes mac tick is the way their OS X marries their hardware.......so check ur imac maybe u didnt install something right or have the hardware checked

For developers writing apps(games especially) for it, there a several possible reasons, maybe Steve Jobs hated games.....ok seriously it could be
1.there are more pc users than macs why would developers sit there and try to port it to a mac when they could port it the consoles and make much more money. And then once they have all this money why would they waste their time with mac and get less people?

2.Because devs don't want to throw away all their profits on paying for Mac licenses ($99 per year.....i think not sure) plus you also have to buy their marked up hardware(approx $1000) to develop

3.For a really long time Macs used Motorola processors instead of intel or AMD. As a result, developing on the mac was a very different process than it was for Windows.

But because apple love you and all gamers you have the option of having windows run on it using bootcamp which is better than hackintoch on pcs

I thought this thread is about programmers giving their view on the best laptop for a specific purpose (which does not exists, itz like tagging a girl a the most beautiful girl in the world but she exists).....not others "disagreeing" with me for typing my own subjective view on things.

I'm 99% sure it's because there are more PC users than Mac users. The same reason virus creators don't bother for Mac

dhtml18:
Well, it was wrapped in nairaland smiles, and indentations could not be seen clearly. Whatever, i do not claim mastery of python anyway, so it is no skin off my nose whether i am right or wrong.

I can write a code that can work in both Java and JavaScript. If i say it is javaScript, i am right. If i say Java, i am still right.

EXAACTLY
for(int i=0; i<j; i++)
{
}

Works in Java and C#. Probably other languages I'm not thinking of now

seunthomas:
OLODO. You just f**ked up BIG.
Its the same dude. Is that not why abstraction was invented and everybody is embracing OOP.
You should try not to call yourself a programmer. very shameful.


You don fall my hand, you know even sabi you dey mentor people. LOL.

Obviously u haven't tried OOP in JS. JS implementation of OOP is quite different from others

GodMode:
Then your programming is null.....

Every programmer has a language they specialize in.......
when a programmer says "lot of other languages" then that programmer is void....

THANK YOU.

You just cannot master all.

Afam4eva:
Ok. Cool.

Btw, how is Vacoas and Quatre Borne?

Lol which Afam is this

ovoSoftware:
Code crackers break 923-bit encryption record

In what was thought an impossibility, researchers break the longest code ever over a 148-day period using 21 computers.

http://www.cnet.com/news/code-crackers-break-923-bit-encryption-record/

Why will they need the power of 21 computers.....for serious hacking you need powerful computers.....great hackers build a custom desktop but the op asked for a laptop. You a right there 3D designers will love this laptop

In computing, there are some tasks that are impossible or not feasible to do with 1 computer. E.g Climate forcast, brutforcing even 128 bit keys etc. That's why there is something called Distributed computing. Meaning the job is shared with other cpus.

No 1 computer can crack a 923 bit key in 1 lifetime ... or at least it doesn't exist yet. So there's no point in the op buying super computers when with the right knowledge, he'll accomplish the same task with a personal computer.

Afam4eva:
Which mobile browser are you trying it on?

Was creating an Hybrid app. I found a solution already

Thanks

bankydirect:
I will be glad if I can get a quict response to this!

My host kicked me out that am taken too much resource on my businesss shared hosting platform. now what can I do?

Upgrade your hostin plan

ari3l:
Let me put it this way,no there is no specific laptop for hacking and programming.

Do you instruct your laptop to write the codes for you? Answer is no, you use your hands code things like for loop, do loop,while loop etc void installKey(), etc so why? If laptop A can do just much,why would laptop B be so lazy to do such?

What your question ought to be is,whats the best OS for hacking, in my opinion I suggest Cyborg Hawk linux, but if you have kali linux, it's good too.

All the big names, just get a laptop,get a skill, and use it to make money.
Have fun

Lol very correct

ovoSoftware:
for programming I would go for macbook pro.....BUT WHY.....welll because
1. the best software for web development exits on OS X eg TextMate and more....it is believed that the best developers are on macs so they built the best tools on macs

2. windows is considered to be slow, complex and unreliable in comparison to OS X

3.Mac OS X is the only platform that allows you to develop for any platform - web, Microsoft windows (bootcamp), iOS , Mac, Unix and Linux


for hacking....I mean serious hacking ....the only laptop I have seen that is close to that of a desktop is the Sky X9W having
1. 64gb ram (DDR4 2666MHz)
2. 5tb of ssd disk space
3. Intel’s Skylake i7-6700K
4. ultra HD (4K) display
5.  8GB Quadro M5000M GPU.
6  3 fans onboard to keep the workstation from overheating
.......this beast will be able to do a brute force attack (to test possible key combinations) pretty well.... but that is only if you have $11,000 to spend


NOTE : the above writeup is subjective

Mehn I agree with the Macbook suggestion.

But the second is weird....very weird. What would an hacker want to use Such config for ?

Laptops like that are meant for 3d game designers or heavy 3d graphics designers.

OP, any laptop with fair config is okay for hacking.... you could get Kali-Linux, Backtrack or Gentu OS to make your hacking life easier
